My opinon, I wouldnt explain anything to them. You are wanting to fix a nice Christmas dinner for them. They need to take into considerations your feelings. they need to realize that this is something you want to do for them and the whole family. Tell them that they are invited to come.. if they choose not to.... it is thier loss. You are a wonderful person and they would be fools not to want to be around you!!!!
