This is friggin awesome.
It means you don't get fixated on one girl because you can get many others, even better than her.
It means rejection doesn't affect you because a lot of girls are also out that night.
It means you can walk away if you don't like the way she is treating you.
It means you don't care about the outcome of the interaction. You don't say "this has to work".
You could care less.
You are abundant and you are cooler than the girl.
