根据短文内容选择正确答案。

Everyone needs friends. What kind of people can be friends? Here are some students’ opinions.

Nick	I think a good friend should always support(支持)me. Also he should know my likes and dislikes. When I'm wrong he should tell me about it and not worry that I may be angry.
Gina	I like to make friends with those who are the same as me. The similarity doesn't have to be about looks, but about hobbies and interests, But the most important thing is that they must be honest(诚实的).
Jenny	I want to make friends with people who bring me happiness, give me a hand and support me.
Mark	I would like to make friends with people who are different from me. We maybe sometimes don't agree with each other, but with friends like these I can learn different ways of thinking.
