ok, here goes the situation
one day, you meet A. she is very pretty, you try to approach her and chat with her because you attracted to her. after you chat with her, you found that she is very nice person too, and she is really meant for you!!! you want her to be your girl friend but too bad she is not available (or she is not ready, or you dont want LDR, or that time you really stupid, or whatever reason la). so you move on......

after 3 years you have a girl friend, B. she is just ok ok only, lets say a responsible and caring girl......but 1 day, you accidentally got to know A, or someone very similar to her and you become her normal friends la.  that time, A or someone like A is available. what would you do?

I have often heard that girls are like monkeys. They do not let go of one branch before grabbing a solid hold of another.

And now, men are like that too.
