DEAR ABBY: I took my grandsons to see a movie. They were looking forward to our outing all week. As we stood in line to buy tickets, I realized I had only a $20 bill in my wallet.

We had planned to lunch on hot dogs and drinks in the theater, but I knew I wouldn't have enough cash. I told my grandchildren we had a problem -- I was short of money -- but I figured I could write a check.

The 7-year-old said, "No, MeeMaw! The sign says cash only." I replied, "That's OK because it doesn't cost much for kids." He piped up again, "MeeMaw, the sign says $4 for children."

As the line to the cashier grew shorter, we decided that we'd buy only one hot dog and one drink, and we'd share.

Unbeknownst to me, a young lady standing in front of us overheard our conversation. When she reached the cashier, she purchased her tickets, then turned to me and handed me three tickets to see our movie. I was shocked and delighted and so were the boys. I tried to thank her, but she was gone in a flash.

Abby, I will never forget that dear girl's kindness and neither will the boys. It happened more than a year ago, but I still think of it to this day and have tried to pass her generous act forward. I hope she sees this letter so she will know what an impact her spontaneous act of kindness had on us. -- GRATEFUL MEEMAW IN AUSTIN, TEXAS

DEAR MEEMAW: So do I. Acts of kindness are like pebbles tossed into a reflecting pool. The ripples radiate outward long after the deed is done.

DEAR ABBY: I know you sometimes enjoy sharing amusing incidents with your readers. Years ago, we lived in a friendly community of row houses with attached garages. I was attending college at the time, and usually returned home around midnight.

My best pal, my cat Peg, would wait for me on top of the garage. When I left the garage, Peg would jump on my shoulders and remain there for several hours after I went inside to study.

One night I was delayed getting home. My next-door neighbor, an alcoholic, came home from a party stewed to the gills around the time I usually got there. There were no lights in the garage, and it was very dark.

Assuming it was me, Peg jumped on his shoulders as he left the garage. My neighbor screamed and yelled. The neighbors came out to see what was going on. The police arrived. Hysteria ensued.

The next day the morning paper had the headline, "Wild Animal Escapes From Zoo." -- MORRIS W. IN ARIZONA

DEAR MORRIS: And I know which one. It was one of their pink elephants.

DEAR ABBY: Please help me. My lover and I have been disagreeing lately and are considering couples counseling. However, he keeps insisting that we see the marriage counselor he and his wife are currently seeing.

I want to make this relationship work, but I think it's inappropriate to receive counseling from the same one that they are currently seeing. What do you think? -- NEEDS THERAPY IN TEXAS

DEAR NEEDS THERAPY: I think you should definitely have some sessions with the therapist who is counseling your lover and his wife. They could prove enlightening. I'm willing to bet the farm that the same issues that have caused him to cheat on her are the ones at the root of your problems with him. And I'm not at all sure that "making this relationship work" would ultimately be in your best interests.

DEAR ABBY: The letter from "Vince in Vallejo" (Jan. 3), the construction worker who is suddenly afraid of heights, reminded me of a similar experience I had at about his age. I, too, suddenly found myself afraid of things that had never bothered me before. I was nervous if my husband drove too fast. I became frightened of heights.

I think that, at a certain age, death suddenly becomes real, either because of the death of someone we know or just awareness of how time is passing. We are not immortal, and for a little while we become self-protective. It passed for me, and I'm sure it will for him, too. -- ALICE IN TROOPER, PA.

DEAR ALICE: You could be right. However, I advised Vince that he should consult his doctor to make sure his problem wasn't of a medical nature. Sometimes a stitch in time ...

DEAR ABBY: You were right on about "Vince" going to see his doctor about his fear of heights. It may not be a lack of courage on his part, but rather his inner ear.

I began having problems with heights several years ago and mentioned it to my doctor in passing. After he ran a few tests, it was discovered that I had inner-ear problems. The slight, subconsciously noticed balance problems I was having were translating into my fear of heights. When I got my balance back, the fear disappeared. -- SARA IN CHICAGO

DEAR ABBY: I was a daredevil in my youth, but it all changed when I became a parent. My fear of heights is also painful, embarrassing and pretty noticeable because I live in the mountains. I guess caring about someone more than myself made me realize how important my own mortality was. -- AFRAID TO LIVE ON THE EDGE IN COLORADO

DEAR ABBY: I am 52 and have been in the building trades all my life. I have been on my share of roofs and high places in my time. My body is also now telling me that it's no longer the place for me to be.

We don't have to show off for the younger dudes -- just share our knowledge with them. At this point in life, our knowledge is a lot more important than our sense of balance. "Vince in Vallejo" should stay on the ground and teach the next generation how to do it right. That's how I learned when I was young. -- "ZAC" OF ALL TRADES IN CINCINNATI

DEAR ABBY: My experience is similar to "Vince's," and I'm about his age. I believe that the loss of flexibility in my knees, which began with the onset of osteoarthritis, has made me less comfortable working at heights -- especially the slope of a roof. Your advice to him was right on. He should not be concerned about any loss of courage. -- BOB IN COOPERSBURG, PA.

DEAR ABBY: I was a construction worker as a young man; now I am a recreational therapist who works extensively with seniors. I have also been a martial artist most of my life and own a small chain of martial arts schools.

My training and personal experience show that as we age, the large nerves in our legs that give us information about our balance, timing and position become less effective. Much of my current teaching is to help seniors reduce their chances of falling.

You can help get the message out that as we age, our balance begins to go, but by building up our leg strength and being mindful of our stepping, we can ameliorate these effects of aging.

Muhammad Ali observed that "the legs go first." At 52, my own legs and balance are not what they once were, and neither are Vince's. No more jumping kicks for me, and Vince needs to stay off the walls. -- SILENT DRAGON IN CONNECTICUT

DEAR ABBY: Valentine's Day is nearly here, and it can be a sad day for people who are alone -- especially for widows and widowers living by themselves. This holiday can be more painful for them than birthdays, anniversaries and other holidays because they are constantly bombarded with images of love by retailers.

I would like to offer a suggestion that can turn an otherwise difficult day into a day for them to look forward to.

Last year, my fiance and I spent Valentine's Day with his widowed grandmother. Her husband has been gone 10 years, and she has not remarried. He was her soul mate, the center of her life. We wanted to do something to make it a day she could look forward to.

Abby, I cannot tell you how happy she was when we told her we would be spending the evening with her. She had the table set for dinner by noon that day. When we arrived, she was glowing. We stayed for hours and listened as she told stories about her life with her husband. We both learned so much that we didn't know about her life and family. We wouldn't trade that night for anything.

As a couple in love, we get to spend every day celebrating our love for each other. We don't need a day set aside to remind each other of that.

Valentine's Day is about love. It doesn't have to be romantic love. We have decided to spend every Valentine's Day from now on with her, so we can make it "her" special day.

Everyone knows someone who has lost the one that he or she loves. I see no reason not to take a little time to make this a special day for them. Such a small gift can make a world of difference. -- BETH IN BAKERSFIELD, CALIF.

DEAR BETH: Thank you for a beautiful letter. From reading it, I know you and your fiance have a wonderful future ahead of you.

You have made an important point. Regardless of the holiday hype, the most precious gift a person can give to another isn't one that's tangible. It's the gift of time.

Although Valentine's Day celebrates romantic love, we all know that there are many kinds of love. On Wednesday, I hope that none of my readers who are unattached will sit at home alone and brood. Reach out to other singles! Rent a stack of videos, pop some popcorn, sit back and enjoy each other's company. Or pick up the phone and call someone to say that he or she is in your thoughts. Everyone likes to be remembered.

For those lucky folks who "have everything," take a moment and thank the good Lord that you are so blessed. And while you're at it, offer up a prayer for the safety of the men and women who are serving our country in all four corners of the globe, as well as their families at home who are doing without them. I have found that doing so puts everything in perspective.

DEAR READERS: Here's your smile for the day. The children will love this!
