Douchebag coworker. Asked me how my work trip went (big client demo) and asked if anything that I was "complaining and whining" about went poorly. Mind you I was bitching about having to clean up HIS SHIT because he completely dropped the ball on the project. I had to go in and finish or fix all of the things he didn't do or did super poorly. I literally just told him to fuck off and stopped talking to him.
