Here are some students' problems. What are they?

"I can't stand your other friends."

My best friend, Kate, sometimes hangs out with some people that I really don't like. I think they have a bad influence on her, and she only spends time with them because they are "cool". Could you tell me if I should bring the matter up with her, or if it would be better for me to keep quiet? I don't want to lose her as a friend.

"I won't help you cheat."

My closest friend, Kim, has lost interest in school and studying. He often asks me whether I'll let him copy my homework. By now I've said not, but he keeps asking me. I told him that I thought we would get into trouble, but he just laughed and told me not to worry. I don't want to put my grades at risk, but I'm afraid to face my friend about this, so I just keep avoiding the topic. How can I get him to stop asking me about it?

"No, I can't do that for you."

Anna is my best friend. We get along well with each other, but she's asking me to do things for her all the time. "Could you help me pick out some new clothes? Would you mind if I borrow your bike? Can you look after my apartment while I'm away?" And these are just a few examples. I've said yes so many times that now I'm afraid I'll hurt her feelings if I say no. Any ideas?
