Before GF - After GF

You will never understand any girl in your life. Every time they speak different, act different, if you are trying forecast any of their action then I would say you are simply wasting your time. Who said nothing is impossible. Trying to understand any girl would be the one impossible thing in this world. But guys are completely opposite. Understanding any guy is so simple. Any guy would behave in two different ways, one is before GF and next one is after GF. Wondering what is GF? Well, GF means Girl Friend. If a guy just broke up with GF, he act as if he is completely broken and his friends are the only hope in his life. But what if the same guy lucky got his girlfriend back, what could be his behavior towards his friends.
