Did it ever occur to you that that the grace period for returning the bike had passed when the injuries happened?
I'm not afraid to "mess up the pretty new bike", I merely only got to ride it less than 50 miles before a friend backed his car into my leg. The bike is very fun to ride, it's fast as hell.
Stop trying to sound like some sort of badass, it's just tacky and useless on the internet. The thing about the internet is you can pretend to be a hardass and get away with it, but it doesn't make you one, k?
Stop belittling people you don't even know; it's uncouth and just plain rude.
