DEAR ABBY: I was cheered by the letter from Mrs. Virginia Harry calling attention to the fact that some seniors have extreme difficulty rising from low or even normal seats. I too have used end tables as seats in doctors' offices.

After months of embarrassment at frequently having to ask for assistance to get to my feet, I developed a self-help trick: When going out of the house, I carry a tote bag containing two firm cushions. The cushions raise any seat four to five inches. I can use these cushions on the seats of cars and on chairs in offices and restaurants, and I cherish the independence they afford me.

Perhaps some other "mobility impaired" readers will find this helpful until the furniture designers come to our aid. -- HELEN PFAFFENBERGER, SAN FRANCISCO

DEAR HELEN: Thank you for an inventive solution that is easily available to anyone who needs it. Not everyone agreed that redesigning the furniture is the answer for people who have difficulty getting up and down, however. Read on:

DEAR ABBY: This is in response to Mrs. Virginia Harry, who considers herself among that growing segment of our population known as "the graying of America." She asked that the furniture industry recognize their need for couches and chairs from which they can comfortably rise.

Abby, let the designers of couches and chairs tend to their business as they will, for we CAN comfortably rise, by building strong muscles around those aging bones.

I am an aerobics instructor and personal trainer who loves to work with people 55 to 93 (the age of my oldest participant). Many seniors have abandoned their easy chairs for fitness walks, aerobics and line-dancing classes, and strength training. When they finally do sit down during their busy daily lives, any chair or couch will do, and they have no problem getting back up when it's time.

I hope your readers will consider a weekly exercise regime to help build their strength. What a difference they'll see in a very short time. Here's to health and fitness at any age. -- CANDY CORLEY, FOXBORO, MASS.

DEAR CANDY: I'm printing your letter as a reminder that growing older does not mean becoming sedentary. A healthy, flexible body is available to those who work for it. Of course, consult a physician before beginning any exercise program.

DEAR ABBY: I am a nursing supervisor at a local hospital. I recently received a call from a nurse's husband stating, "My wife will not be in to work today because there's been a death in the family."

I asked the husband in a sincere and compassionate voice, "Oh, I'm very sorry ... who died?" The husband replied, "Uh ... uhh ... Who died?"

I replied, "Yes, who died?" The husband covered the phone and returned several minutes later and said, "Oh, it was her father-in-law."

I expressed my condolences, then innocently asked, "Isn't that your father?" He then said, "Oh, yeah ... my father died."

The lesson to be learned is when dealing with life and death on a Monday morning, be prepared. -- SUZZETTE L. HAACK, SAN DIEGO

DEAR ABBY: My 15-year-old daughter is pregnant and in the ninth grade. Her baby is due in five months. The father is 20. He has been to bed with a schoolmate of hers (also 15), and is now with a different girl on a regular basis. All of them are underage.

Abby, I have raised my daughter with no help or child support since her father and I divorced nine years ago. I worked two jobs and tried to be a good mother. I thought I could trust her. She went to a counselor twice, but refuses to go again.

I suggested she put the baby up for adoption, but she wants the baby and thinks she can take care of it and go to school.

What can I do about this? -- TROUBLED MOM

DEAR MOM: Call the young man and, in as friendly a manner as possible, ask how he intends to provide for his child. Keep the conversation cordial, since you will need his cooperation.

If he refuses to accept his responsibility, the district attorney's office in your city will assist you in getting child support from him. The D.A.'s office can also help you file charges of statutory rape, although the young man would be a better provider if he were out of jail and able to earn decent wages.

In 1990, I published a letter from a teen mother in Phoenix, trying to warn other girls of high school age. Perhaps if you show it to your daughter, she will realize what she can expect if she continues down the road on which she's headed. Read on:

"DEAR ABBY: ... I hear my friends telling me how much they'd like to have a baby, and how they wouldn't mind getting pregnant. All they think of is how much fun it would be to dress the baby and show it off. The truth is, once you have a baby, you don't feel like going out anymore. You don't anticipate the incessant crying, getting up in the middle of the night for feedings, the dirty diapers, the spitting up, the constant washing of clothes and bottles, and most important, the expense.

"I spent $600 in baby-sitting costs alone between March and May just so I could go to school and graduate -- $600 that I didn't have. That meant I had to get a job, which meant more baby-sitting costs.

"I was not, and still am not, emotionally prepared to be a mother. The stress is incredible. For the rest of my life, I am going to be a mother. If I don't feel like being a mother at some point and want to just go out and be an 18-year-old -- a typical teen-ager having fun -- that's too bad, because I will always be a mother first.

"Babies are wonderful gifts from God, but I believe they are meant for people who are emotionally and financially ready for them."

Of course, the purpose of the young mother's letter was to prevent other teen-age girls from having to experience what she was going through. In your daughter's case, it's too late for that. But perhaps when you show this column to her, it will help her to recognize the enormity of the lifelong responsibility she's assuming -- unless she recognizes the wisdom of putting her infant up for adoption. I wish you both the best of luck.

DEAR ABBY: In response to "Call Me William," I wish to quote the following verse that my husband, Bill, was told by his father:

"My mother calls me William,

"My father calls me Will,

"My sister calls me Willie,

"And my friends all call me Bill."

My husband quoted this verse many times when new acquaintances asked him how he preferred to be addressed. -- BILL WOLFORD'S WIDOW, ALICE, IN DAYTONA BEACH

DEAR ABBY: I was intrigued when I saw the letters in your column about forgetting people's names and trying to bluff. They reminded me of an incident that happened to my father, who is a 79-year-old Baptist minister.

Dad worked many jobs over the years. He had a "paying job" to raise us kids, and on the side he preached. He met people all over the Southwest, and they remembered him because he was educated, articulate, poetic, literate, compassionate, forgiving and loving. (He still is, and he still preaches that God is a loving, compassionate and forgiving entity.)

Dad can remember the faces of most of the people he has met, but not their names or the context in which he met them. One Sunday he returned to a church where he had served as an interim pastor. A lady walked up to him after the service and said with tears in her eyes, "Brother Clark, I can't tell you how moved I am to see you again. I haven't seen you in 10 years."

She chatted on about how happy she was to see him, and Dad tried vainly to remember her name. When she mentioned how much her husband had always thought of "Brother Clark," Dad put out a feeler based on that continued theme. "And just how IS your husband?"

"Still dead," was the much colder reply. It turned out that the last time the lady had seen Dad was when he had preached at her husband's funeral!

Dad not only raises people's spirits when they are grieving, he also raises the most beautiful flowers in Clinton, Miss. (just outside of Jackson). My mother is deceased now, but one of my favorite stories about my parents concerns a woman who stopped quite often to admire the gorgeous landscaping. One day the lady turned to my mom and asked, "How much do you pay your yardman?"

"Nothing," Mom replied. "But I have to sleep with him." -- KAREN CLARK, FORT WORTH, TEXAS

DEAR KAREN: Your letter is a day-brightener. You are fortunate to have been raised in a loving home in which laughter was not a stranger. That reminds me of a quotation I treasure from Wilferd (cq) Peterson: "Laughter is the best medicine for a long and happy life. He who laughs -- lasts."

DEAR ABBY: Mothers-in-law are so often given a "bad rap," I just have to tell you about mine.

Recently my marriage was faltering. My husband, "Jack," is a complex man whom I had always had great difficulty understanding. I felt I had tried just about everything, and was one step away from filing for divorce.

Out of desperation, I called my mother-in-law (I'll call her "Adele"). She listened as I poured out the story. She did not judge, criticize or condemn either one of us. She supported her son and me equally. Adele provided some keen insights into Jack that I didn't have. In a kind and gentle way, she also helped me to see where I needed to improve.

I learned a lot about my husband and also about myself from Adele's wisdom, and I'm putting what I learned into practice. Jack and I are staying married, and our marriage is growing stronger.

I thank God for my mother-in-law every night, and I pray that when my children are grown and have spouses of their own, I will be to them the same wise and loving mother-in-law that Adele is to me. -- MICHELLE IN GEORGIA

DEAR MICHELLE: What a beautiful tribute to your mother-in-law. As your letter so accurately illustrates, there are times when it takes more than two to make a marriage flourish. Thank you for sharing that valuable lesson. Adele sounds like a jewel.
