Why do we chase the opposite sex?

Why do girls go chasing after boys?

Why is that?
Is it because they can't live with out them, or they are just afraid that they may never end up with someone like that again?

Really why is it?
Why isn't it boys chasing after girls, its always girls chasing after the guy!
Its like a race, but you only win by winning the person you want.

Maybe its because, Girls are used to getting hurt.
But don't want to be hurt, so they follow, they chase.
They do what it takes, to be with them.
