• Don’t surprise the host with last-minute dietary requests. 
• Don’t show up empty handed or with a surprise dish.  It’s not the day for a green Bean Casserole competition.
• Don’t expect oven space.  Lug over your air fryer or something.
• Don’t arrive early or show up starving. 
• Don’t overserve yourself.  This goes for alcohol too!
• Don’t overstay your welcome.  After desert and coffee…leave!

RUDE!
