Wow. I'm guessing you have no idea who Hannah is... it was probably a woman that did it... revenge for a best friend...

If there is no possibility she was a drunken one night stand or something, I don't know.

My name is Hannah! (but it wasn't me)

terrible man just terrible ud think that the guy who was gonna smash ur car would have done a lil research to make sure u were the right guy

don't act like you don't know what you did!!! from, hannah haha lol

You don't even know the name of the person you mistreated? Tut tut ;)

wow, that's shitty.

You file a police report, then get a bunch of CSI stuff like finger print dust, gather finger prints n DNA and send them to be identified and then proceed to vandalize their cars

Find Hannah. Destroy her. :p That sucks dude, file a police report.

Maybe the fact that you don't remember who she is might have something to do with it... or maybe you have the same car as someone who's a douche. Lol.
