The Unfamiliar Friend

This is confusing, everybody is like can you become friend with someone before liking someone. People always become friends after get familiar with them. But this reverse it, instead we become friend first after that we get familiar with them. 

During school times, it happens, classmates level of friends or colleague level. Do you found about  it. It happens during working relations. You are doing a cooperation with somebody on a work. It becomes a temporary friends. Ideas are shared instead of talking about hang out, talking about things people busy body about.

In classmate level, you talked about school and homework with someone, you just merely know his or her name. Teacher asked to work on a school works in a team, so you becomes teammates. So just we don't observe about it, we do have friend which we don't get familiar before we becomes friend.
