They're not, they're regular human beings just like you. The only reason a girl might be too cool for you is if you go around thinking that she is. I basically try to live life by the "it's too damn short not to give it your all approach," and this applies even to simply going up to a pretty girl and initiating conversation.Link55 said:
This doesn't even mean you're hitting on her, just trying to make friends. Relationships of all sorts are extremely important and you shouldn't ignore 50% of the human population just because they have boobs. It's just not a healthy way to live. Simply put, put effort into enjoying your life.
