Biggest Pet Peeve Discovered....people chiming in in chat during the game

When you are typing to you jungler and having a dispute and the support or adc chime in with their unsolicited 2 cents.

Seriously, if the conversation doesn't apply to what you are doing in your lane at that point just keep your mouth shut and let them sort it out instead of saying something that is going to aggravate one of them, and probably make them type back to you, get them unfocused, possibly tilted, along with drawing you into a back and forth distracting everyone.
