Can’t agree with Lizzy. A wedding is certainly not the place for groom’s father to air grievances between he and wife. Attention seeking in lowest form!! Personally, I wouldn’t be laughing about it ever! I agree wholeheartedly with Suz’s reply.
I certainly would not let outside hotter air inside! Close up everything and hang a wet towel from your fan. I agree wholeheartedly with b“Bronze” comments.
