I remember in my Intro to Java class, there was a guy I loathed with all my heart and soul. I ended up moving all the way across the room and even then we got into a pretty intense confrontation.
Most people in the course knew nothing about programming and had no interest in it, as it was required even if you wanted to deal with hardware or networking. As such, it was often slow going and some people had zero aptitude for it. Unfortunately, the guy I'm talking about, he already knew some programming and proceeded to let everyone know by sighing loudly, tapping his foot, and loudly muttering things like, "oh, come on," when someone was stuck. The professor would be talking and this jerk would act like a one of those little boys who have to stay beside their mom when she's shopping for dresses. He'd even roll his chair around like a brat.
Because I was initially right beside him, it drove me absolutely crazy. At first I would bring my earphones and put them on the moment I sat down, even if I wasn't listening to anything, because sometimes he'd complain to me or, even worse, talk about his car.
One day I'd had enough and just moved my things to another workstation. However, he was STILL annoying and I ended up telling him so. I don't know how close we were to fighting but I really wasn't too bothered by the prospect.
