Breakfast Topic: Recruiting regrets

I've never recruited anyone to the game (I have helped convince a friend to play, actually, but the truth is that he didn't need much convincing), so I've never imagined a situation like the one that faces Aerna: she and another friend recruited a third friend to play WoW with them, but now he's become nothing but an annoyance. He begs for powerleveling, doesn't know how to play his class, and generally makes a mess of things, forcing her to run away from him to play Horde (so it's not a complete loss..).

So what can she do? I'm trying to figure out why they're friends in the first place-- can it really be true that someone you like hanging out with in RL can turn into a menace inside Azeroth? It could be that he just needs some guidance on ingame etiquette and strategy. On the other hand, I can definitely see how two people who don't have much in common (co-workers, maybe) might find their relationship pushed to the limit when brought to the world of Azeroth. Have you ever recruited someone to play the game that actually ruined the experience for you?
