"can you roleplay that we get along?" Fair question?

[The Pilgrim]

Conflict among characters spreads quickly into conflict among players. Better to cut it short.

If your friend ecided to play a kleptomaniac who can't help stealing from the party, that was her choice, and the rest of the characters, and players, have no obligation to endure her. If I find out that a partner is stealing from me, I stop working with that person. Likewise, if my character finds out that one of the party members is stealing from the group, he would boot her out. Unless he is stealing more than her from the party. But then you aren't playing Dungeons'nd Dragons, you are playing Bastards'nd Backstabbers.
