There is still time to back out!
Andy, this is a TERRIBLE deal. You are getting robbed - but the silver lining is that you can still say no before March 12th. That's all you have to do. Say, "I've thought about it, and after I came down from my paint huffing bender, I realized what a stupid deal I'd cut. I'm out." That's it. Problem solved. I fear you're too proud to realize your mistake, but don't be. We'll love you for saying "I was confused and sweaty and just said yes so I could get to the bathroom." T-minus 13 days and counting, Reid.
