Though it's commonly a p2p frustration, I thought I'd share it here since f2p can do this if whispered first.

Arguing with the wrong damn person for a minute straight, and feeling awkward as hell when you realize you were bashing heads with someone who didn't do anything to you. Maybe you people aren't as clumsy as I am, but this has happened multiple times with me. Sometimes when I'm trying to tell someone what gear they need (but I'm also talking to someone else about a different subject). Then I get a reply "Lol, no I don't", and I'm trying to convince the wrong damn person for the next 2 and a half minutes before coming to my senses.
