Tell me who your friends are and I will tell you what you are.

Hmm. In my opinion, this sentence is not entirely true. I mean, I have a lot of friends, belonging to various circles, and each circle being of a different kind. But it's not like I'm like all of them. We still have differences.

This sentence is definitely not correct. But it seems that some people in the society goes by it while choosing partners. I have a friend who sleeps around a lot. Here I am a virgin. My boyfriend has a friend who parties like crazy. But my sweet love never goes anywhere. I suppose the line takes into account community system. Some people prefer to join clubs or groups where only strangers of their personality are available. For instance, in our school, I saw some Jewish people joining only the Jewish club and Muslims going for some Islamic club. In that case, they can be taken as too religious. Meanwhile, there are those who prefer to join clubs of the subject they are majoring in. The mission for all of them is just one and that is to hang out with like minded folks. But others do not do the same. They are happy to be with everyone. But that does not mean they are letting others personality take over themselves. That is why, I will say that the sentence is not true for all.
