My DH acts so damn immature when he's around his siblings. I know they don't see each other that often, but it's ridiculous. Yesterday, all of us were in the elevator at the hotel and some guy got on and DH made a comment about his shirt and all his siblings started snickering and it was just so FUCKING rude. The guy kept looking at them and then at his shirt and when he got off the elevator, they just kept laughing and snickering and whispering. When I got him alone in the car, I reamed him out. I told him how rude they were being and that it just was not acceptable to act that way in public. Of course he felt bad about it, but he didn't apologize. He just said "Oh well, we weren't laughing at that guy". I said it didn't matter; they were still being super rude.
