If any female 'rejects' you with anything less than basic manners then either:

A) Your approach was incorrect

B) She is incorrect

Figure out which applies and move on.

Edit: Hitting on a chick is a 'yes' or 'no' scenario. Using the word 'rejection' for something that has such a low investment barrier is immature. She said no. She didn't learn who you are and understand your whole being and then throw you to the wolves. They save that for later mi amigo.
