Is it difficult to understand Girls?

hi,its not general difficult.its most difficult.we can swim sea,we can reach sun...bu understanding a girl is so hard.

I'm a girl that' why i can say that in most situations, Girls are easy to understand. I've got a lot of guy friends maybe whats driving me insane is that why most of my friend's girlfriends say yes when they mean no and say no when they mean yes. coz i'm really not like that. i'm a transparent person and i am not pretentious.
