Sounds like me. I rarely talk to other people on online games outside of WoW. I just come in, smurf trout up and leave.

My finest moment in WoW was on my Priest, joining Warsong Gulch to find out flag carrier in our flag room being pummelled on by 7 Horde. Kept him and myself up whilst he killed them all. We never said a word to each other before or after - but we shall both remember how glorious it was.
