when you let a ex, usually recent or that you know still has feelings for you, know that youre hooking up with someone new. basically, so they dont hear it from a third party and get pissed you didnt tell them.
Carrie: so he's banging some new girl...

Carrie: no, i had to run into pics of them on her myspace...
