Many girls are foolish, thinking that love is an emotional thing that can be persuaded by persistence, patience and effort. So you believe that if you constantly pursue, cease to resolve, and do not stop sacrificing, then will turn a turn look back.
There are also many girls who are pursued and flirted with by so many boys, but are always bluntly refusing to run after a silhouette that has never been - and will never - belong to them.
It seems that for love, the more you do not have it, the more you desire it. For things that are too simple, too light, people do not know the respect. Instead, it is difficult to duplicate the new people desire to conquer. And also for that reason many girls love to give their hearts to others, though others are indifferent and indifferent.
