I also disagree with the notion that once a player agrees with a house rule or a rulling the discussion is over, and they have to stick with that verbl contract. Maybe the player didn't know at the time how the rulling would bother them, or how it would subtract from their enjoyment of the game. If a player brings up a problem with a rulling they had agreed at the start of the campaign I'd reopen the discussion with them (before or after the gamming session of vourse) and try to acomodate their feelings, evaluating if my goal with the rulling was met and if I can help the player feel better about the game. No rulling agreement is more important than the overall enjoyment of the game in my opinion, and everything is up to discussion and revision at any time (expect in the middle of the game, if it can be avoided).
