Confused Kid Playing Team Fortress 2

Learning the controls for a new game is a challenge. Especially if you're coming from a console game like Call of Duty and trying to learn PC controls for Team Fortress 2. This kid's confused by more than the controls. He thinks everybody he's playing against are "hackers" and keeps trying to bring up his "sniper quick scope thing." There's also a lot of indistinguishable complaining. Then he finally gives up and decided to play something he knows how to play, Call of Duty.
