usually only if you need something to back your car over...

well, that's true too. and thank you very much! may I ask what this ex of yours came in handy for?

oh hell yes. ! that they definitely can be. I know which one of my ex gfs I would want over after a heartbreak!

oh, it was a mutual college breakup. she was a foreign exchange student and we knew it would end. didn't make it easy, but we still keep close on FB. She was amazing and sweet. I miss her a lot.

i have only one answer to your question: boobs.
