- You sign personal correspondences with your character’s name.

The most commen one in my group is that we give every singel movie-charracter alignment, class and race.

These actions fit nicely into this list, Are! 😀
Oh, you mean you don’t ask strangers drinking alone in bars if they’re offering a quest?
That was #11, Michael 😉
