Do you read advice columns in newspapers and magazines? Do you think they are helpful to everyone

who reads them? Here are some:

Dear Sally,

I've got a problem. My good friend Lana in my science class asked me to lend her my exercise book so

she could copy my answers. Should I do it. Sally? I don't want to,but I'm afraid that if I don't give it to her

she won't be my friend any longer.

Carmen

Dear Carmen,

Of course you can't give her your exercise book. That's cheating, and you could get into big trouble if

you do that.

Sally

Dear Sally,

I was at friend's house for dinner last Saturday. During dinner, I broke a beautiful plate. It was my

friend's favorite wedding gift. I wanted to pay for it, but she didn't agree with me. I feel bad about it.

Kay

Dear Kay,

I think you did the right thing. It was important to offer to pay for it,but it's not surprising that she

said no. Perhaps you could give her a special gift instead.

Sally

My son is 24 years old. He finished college last year,but he can't seem to find a job that he likes.

day. Also I've been cooking his meals.
