Dear Abby:

The letter you printed from "Rehabilitation Counselor," advising people with seizure disorders about state agencies that assist individuals with disabilities to become gainfully employed, was excellent. However, I would like to add more information:

Canine Partners for Life (CPL) is an organization that provides "service" dogs to people with various disabilities to assist them in leading more normal lives. These service dogs can be trained to detect a seizure up to 30 minutes before it happens, enabling the individual to take precautions required to possibly prevent or alleviate the problem.

Peter Esherick, Orefield, Pa.

I am familiar with service dogs and the important role they can play in the lives of people with disabilities. While most of us are aware that Seeing Eye dogs perform an important function for sightless people, special dogs can also be trained to retrieve items, open and close doors, provide stability when walking, and alert their owners to oncoming seizures.

Canine Partners for Life can be contacted by writing to P.O. Box 170, Cochranville, PA 19330-0170. The phone number is 610-869-4902 and the fax number is 610-869-9785. The Web site is www.k94life.org.

Dear Abby:

I have been with my girlfriend, "Adrian," for two years. She has always been obsessed with my past. Recently, Adrian went through all my old letters from ex- girlfriends, dating back to early grammar school. Now she is demanding that I burn them. I have refused because she read them without permission, disregarding my privacy.

Is it wrong to keep old letters? I've always assumed it's okay until I get married -- or at least engaged. To me, the letters and notes are a "diary" of sorts.

What's your opinion?

Your girlfriend is jealous, insecure, nosy and nervy. She has no right to "demand" anything from you. If I were you, I'd keep the letters and give Adrian a change-of-address form. In the long run, you'll be happier.

Dear Abby:

My husband and I enjoy eating at buffet-style restaurants. Drinks are usually brought to the table by servers, who also clear away empty dishes and attend to any additional needs we may have.

Our question: What percentage of tip is appropriate? Some patrons leave none at all. Awaiting your reply.

In a buffet-style establishment, the appropriate tip would be 10 percent -- or more, if the service is outstanding.
