My first day (using keyclone anyway, I had manually multiboxed for years before then) all of my characters were running different directions when I tried to use the innkeeper in Goldshire. (what was I doing alliance side? To this day I don't know why I or anyone else plays alliance, sorry)

Then some jerk who wasn't quite grown-up enough to be a jerk says, "Learn 2 use keyclone a little better"

I stewed over that passive-aggressive insult for my first week as a keycloning multiboxer.
