I would necessarily characterize sitting out a game as taking my ball and going home because I didn't get my way. My friends like to play Vampire but I don't. I'm OK with sitting out that game and giving them a chance to play it rather than play something that I won't enjoy very much. Our friendship isn't threatened by that. If anything, that strikes me as a reasonably adult reaction - letting other people have their fun even if it means I'm not participating in it.
Oh, sure. With that I agree. That's not what I was talking about though. I was talking about not being allowed to use a couple of feats.
