Who here has been single all their life.

（´Д｀;;) i get really nervous around girls for some reason, especially when i like them. Is it game over for me?

Well you have to take into consideration that chit-chat is a form of ritual wherein peoplehave no particular topic in mind and are in hopes of engaging in deeper activity.  Another hypothesis is that it serves to build labels and characterizations with others.  Girls may talk to reaffirm their clique bond.  Guys may do so to reaffirm group identity as virile.  Again, this all goes into the self-monitoring/self-fulfilling/Spectacle hypothesis of sociology.  It's not necessarily a bad thing, though seemingly moot to those not in the engagement.
