He is not my type.他不是我喜欢的类型

有的时候可能就是这样，喜欢你的人你不一定喜欢，你喜欢的人也未必喜欢你。所以，那么多男男女女都在这寻寻觅觅中昏昏顿顿...

听听这段对话：
(At a party)
A: Mary, look, Tommy's here. Have you heard about him?
B: Just a little bit. He's said to be very successful in his business.
A: You know, he's got crush on you. But he's too shy to speak out.
B: How did you know that?
A: I happened to meet him in a cafe. He told me about this.
B: But I don't think he's my type.
