DEAR ABBY: I am 29 years old and have been reading your column since I was 10. Becoming a high school teacher was always my dream. I graduated from college with a degree, but not in secondary education. I needed to begin working full time to support myself, so I never considered going back to school to certify.

Because I admire the field of education, I offer this tiny contribution for teachers everywhere:

TEACHER-PARENT AGREEMENT

I will teach your child to read -- if you teach your child to have an open mind.

I will show your child how to solve a math question -- if you show your child how to solve his/her problems.

I will tell your child about war and its aftermath -- if you tell your child to treat others with equality.

I will introduce your child to Shakespeare -- if you introduce your child to others he/she may not now understand, but will come to respect.

I will point out the many places on the globe -- if you point out that the world is open to him/her.

I will explain the stars and planets -- if you explain how your child can surpass them.

I am able to teach your child some things, but TOGETHER we can teach your child everything and help your child to grow. -- VERONICA M. DE CRESCIO, CROYDON, PA.

DEAR VERONICA: Something I've learned over the years is that when people feel they have a calling, they should follow it.

It's never too late to realize your dream. With your degree, perhaps you could begin working now as a substitute teacher. There is a great need. It could serve as a giant step toward getting you back on track. Please consider it.

DEAR ABBY: I am 100-plus pounds overweight. My husband has repeatedly asked me to lose weight but I have not. We no longer make love.

My husband is cordial and continues to provide beautifully for me and the kids -- he's a great dad. Do you think it's fair that he is withholding sex from me? I think he expects too much, as I love to eat. Now he has moved to another bedroom and claims he is turned off sexually. -- FRUSTRATED WIFE

DEAR WIFE: Although everyone has the "right" to weigh whatever he or she wishes, your weight gain has jeopardized your marriage.

By moving to another bedroom, your husband has given you an important message: Your marriage is in serious trouble. If you think it is worth saving, ask your doctor for a referral to a registered dietitian so you can begin to lose the extra pounds you have put on.

Next, consult a psychotherapist. The fact that you have chosen your love for food over your love for your husband needs to be addressed.

CONFIDENTIAL TO MY READERS: Have a Merry Christmas, but please keep in mind: If you're drinking, don't drive; if you're driving, don't drink.

DEAR ABBY: After many years of part-time college classes squeezed in between working and parenting our children, finally at age 42, I have earned my bachelor's degree. I skipped the traditional graduation activities, such as the commencement exercise, but I did order announcements to send to close friends and relatives.

My husband said I shouldn't send announcements. He views them as bids for gifts, which he thinks are for 20-somethings just starting out in adult life.

Abby, I mailed the announcements anyway. Some people did respond with gifts, none of which were inappropriate or overly expensive. Others brought bottles of wine to our party to celebrate my accomplishment. However, I would still like to know if announcements for mature graduates are in poor taste. -- PROUD "OLDER" GRADUATE

DEAR GRADUATE: Announcements of accomplishments such as obtaining one's degree are not in poor taste. It's never too late to celebrate becoming the person you want to be. Just because it took you longer to get your degree than those who were fortunate enough to study full-time, no one should minimize your hard work.

Congratulations on your tenacity and your degree. You are a role model for your children and other adults.

DEAR ABBY: I am a 17-year-old high school student. Until I was 13, I did some modeling and my mother entered me in beauty pageants. I constantly worried about my appearance and considered myself ugly if I didn't win. At 13, I began what my mother called "the ugly years."

At my last pageant, the judge told me I was gaining some "chub" and needed to lose weight. After that, I became bulimic for a year. Fortunately, I realized what I was doing to myself and stopped bingeing and purging.

During the four years I have not competed in pageants, I've become happier and more self-confident. My mother recently told me that now that I'm through the "ugly" stage, it is time to begin modeling again.

Abby, I don't think I can do it. I never told my mother about my bulimia, and she refuses to listen to my reasons for not wanting to model. I don't want her to know about this disorder, especially since I am over it. What should I do? -- NO NEED TO SHOW OFF

DEAR NO NEED: Tell your mother exactly what her ambition cost you the first time around. It's time she stopped projecting her own ambitions on you. At 17, you are nearly an adult. Under no circumstances should you allow yourself to be pushed into a career that's potentially so damaging to your physical and emotional health.

DEAR ABBY: My brother-in-law's father recently passed away. We had met him several times, but were unable to travel to the funeral services.

My husband and I want to share our sympathies with the family, but we don't know to whom we should send our condolences -- my brother-in-law, his mother or both. What is proper in this situation? -- WONDERING IN WASHINGTON

DEAR WONDERING: Send an individual note of sympathy to each of them. While one letter might suffice, they are both grieving and would appreciate a personal message acknowledging their loss.

DEAR ABBY: Hello? Is anybody home? How could you agree with "Lucy in Cheyenne, Wyo.," who admonished married couples not to shower together because they leave the children unsupervised when they do? Tell that ice cube to get a life!

Are we to assume that single parents don't bathe? Or that in a two-parent household, Mom doesn't shower unless Dad is at home to watch the kids? Do they take turns sleeping?

Obviously, Lucy never had kids. And, with her negative attitude about physical closeness, she probably never will! -- JOYCE IN DOLTON, ILL.

DEAR JOYCE: Cool off. Lucy and I both stand corrected. As long as the child is secured in a playpen or a child-proofed room, it's probably going to be just fine if the parents take a shower break. Read on:

DEAR ABBY: I am so steamed, I can hardly sit still to write you!

As an extremely busy mother of three active boys (one with special needs), I want to tell "Lucy" to MYOB.

Couples have to give up a lot (albeit willingly) when their children are born. Sneaking a few private moments in the shower while their little ones are asleep or behind a security gate is neither neglectful nor unsafe.

Why? Baby monitors! They are so sensitive you can hear your child breathing, much less waking up and crying for attention.

Loving, affectionate parents who enjoy intimacy are among the greatest gifts you can give a child, assuring them of a stable home life. -- MAD REDHEAD IN TEXAS

DEAR MAD REDHEAD: That's true. Couples who play together usually stay together.

DEAR ABBY: "Smokeless but Outnumbered in Pennsylvania," who dreaded the thought of her heavy-smoking in-laws holding her newborn baby, has a legitimate concern. Many smokers have the mistaken idea that their secondhand smoke is a gas that is "gone with the wind" when the cigarette goes out.

Quite the contrary. Cigarette smoke produces microscopic particles of carcinogenic substances that land on clothing, skin and hair. These particles are stirred up with every movement and drift into the air and can be inhaled by those around them long after the cigarette is out.

People who are subject to secondhand smoke have a four times greater chance of getting lung cancer than those not exposed. As a respiratory therapist who works in pediatric intensive care, I am always outraged when I have a pediatric patient who is struggling to breathe, and Mom and/or Dad and/or relatives come into the room reeking of cigarettes. I try to explain that even though they go outside to smoke, they are bringing particles into the room that have clung to their hair and clothing.

Smokers should take a paper towel and wipe down the windows of their cars. That yellow stain on the paper towel is not a gas but an accumulation of microscopic particles that also lodge in people's lungs.

I would urge "Smokeless" to allow her in-laws to hold her baby only after they shampoo, shower and put on clean clothes since their last cigarette. A baby can't defend itself. If her husband won't, then she has to. -- BOB CRONIN, CAPE ELIZABETH, MAINE

DEAR BOB: You have written a powerful letter. If it convinces just one set of young parents to assert themselves on their child's behalf, then it was well worth the space in my column.
