One broken confidence destroyed two reputations.
Editorial note: I don’t think this one quite works, and since I’m fond of the idea behind it, I’m going to go all Director’s-commentary and belabor the point.

However bad the other person might look, you’ve indisputably shown yourself to be untrustworthy, and people remember things like that.
