Should friends be different or the same? Different people have different ideas. The following is what four of my classmates say.

My name is Susan. I am outgoing. I like to have friends who are similar to me. Both my best friend Linda and I like traveling. We went to Italy with our families last summer vacation. We stayed there for two weeks. Next year we want to go to Paris.

My name is Mary. I like to have friends who are different from me. My best friend Betty is shorter and more outgoing than me. I am quiet and I like reading very much. Betty likes sports and she plays ping-pong well.

I’m Peter. I like to have friends who are like me. It can be very helpful. I’m a little quiet and my good friend Rick is quiet, too. Sometimes I don’t know what to do with my problems and he can tell me what I should do, because he knows about me better than people who are different from me.

I’m Bill. I have both kinds of friends. I think it is important. That makes my life more interesting.
