I wouldn't agree that girls have to be misterious... In fact I think it's a stupid idea... I always tell the guy when I like him even though he may not like me back. I do it for my own state of mind and to feel good with my inner self LoL anyawy I guess some girls are just too shy to speak of their feelings or they just don't want the guy to know... I know some guys who will never tell the girls that they like them because they just don't want it. it's strange but it's true... I think we should speak honestly our mind.
*Nods in agreement* so true .. i always doing the same ..no matter what will happens its better to speak your heart and be honest with yourself and others ..
