Recall something in the movie 'Hitch' that goes like this:
'When a girl says she is too busy to think about relationship, it
means that she hasn't met that some1 who is able to sweep her off
her feet to fall in love with that person', unfortunately that
person will not be u cos she only regards u as a good friend, thus
she still tok with u, goes out with u to avoid losing u as a
friend.
If u still want to ask her if u still stand a chance, make sure u
manage to sweep her off her feet b4 asking.
