Inconsiderate guests ruin the spirit of Christmas party

I don't mind throwing Christmas parties, but some guests really bring out the Grinch in me
, but I hate dinner party guests.
This is especially true at Christmas, and fully applicable to my spoiled set of friends. I think they tolerate and indulge my attempt at hospitality rather than truly enjoy the home-cooked festive cheers. Obviously, my little festive gathering can't compare to their VIP dinners with Karl Lagerfeld or Kate Moss. As one of my frienemies suggested as a backhanded compliment, "Darling, I love your party because I can wear something I love for the second time."
The annoying part actually begins way before my soiree. Trying to figure out how many people will come is a drag. There's always someone who RSVPs at the very last minute. "Yes, we're coming tonight!" I guess they assume I am like a well stocked restaurant ready to churn out extra canapes in an instance. Sorry. Reply in advance or you will be removed from my invite list.
