Arggh stupid bitch I hate people like that, why can't everyone be honest and tell the truth when they f**k up.
I was right behind an accident once and I stopped straight away to be a witness. The guy at fault (a taxi driver, surprise surprise) was already trying to worm his way out of it, till I walked over and said, Are you joking? i saw you change lanes straight into the side of him!
He STFU then and I was never called up about it so he must have taken the blame.
