DEAR ABBY: This is another one of those "I never thought I'd be writing to Dear Abby" letters. However, because of your response to a letter concerning jury duty, I felt an obligation to set the record straight.

Obviously, you have never been summoned to jury duty. If you had, I doubt you would have answered as you did.Being summoned is one thing; serving is another. You can sit around for a month waiting to be impaneled; then you have to deal with the defense, the prosecutor and judge, who ask you more questions than they ask the accused.

After the trial is finally over and a verdict is reached, the judge either reverses the decision or throws it out.

This kind of treatment makes people want to serve on a jury? Not me! - BEEN THERE IN OHIO

DEAR BEEN THERE: I agree with Judge Boldt, who wrote: "Jury service honorably performed is as important in defense of our country, its Constitution and laws, and the ideals and standards for which they stand, as the service rendered by the soldier on the field of battle in time of war."

I rest my case.

DEAR ABBY: I am a schoolteacher, and children seem to take a special liking to me. I live in an apartment complex that has a lovely pond with ducks. I often go to the pond with a sack of bread to feed the ducks.

My problem is that children come up to me and want to help feed the ducks. Abby, I could be a kidnapper or child molester. I almost want to ignore or discourage them because I don't want them to think that all strangers are as safe as I am. I would like to tell them not to be so trusting and friendly to strangers because some bad person could kidnap them. These children live in or near the complex.

What are your thoughts on this, Abby? - TROUBLED IN VIRGINIA

DEAR TROUBLED: When you are approached by children - as you surely will be while feeding the ducks - tell the children that they are safe with you, but to remember that not every stranger is an OK person.

Be sure to stress that they never should accept any kind of gift - candy or money or anything else - from a stranger. And they should never under any circumstances get into a car with a stranger. Use the opportunity to educate these children about the dangers of strangers.

DEAR ABBY: I really like this guy. We were going out for a while, then this great guy moved. I really want to get in touch with him, but I don't know his address.

His father lives near me. Should I ask him for his son's address? If so, should I do it in person or on the telephone? I don't know the man personally. Abby, please advise me. - NEEDS ADVICE

DEAR NEEDS: If this guy had wanted to keep in touch, he would have left his address and written to you, since he knows yours. Therefore, it's safe to assume that he isn't interested, so contacting his father would be a big mistake. (In this day and age, if you ask a father how to get in touch with his son, the father might think that you are in some kind of trouble.)
