To some of girls, boys can be very green. Great personality, will do anything for ya. 
 but on the other side, if you get too comfortable with you being nice and obedient to them, when they too sure that you won't leave them, when you got to taste the pride of being a man, when you bow down to them and they find it satifying ...... they can show you their dark sides. 
 be known that a boy can change, they can literally change.
