It never fails, you always have the one person in the group who thinks they can affect an accent… and they can’t, they really can’t. If someone were to hear them outside of your little group they would assume that said person is somehow making fun of the foreigner in the room. The results… aren’t always pretty.
Oh, and it never fails, your characters will die at least once, maybe three times, before you even finish your main quest. The only difference is that someone will somehow make sure you survive, even if it’s the DM taking pity on you (or really, wanting you there in that epic boss battle he designed specifically to fight your character).
