True but when you know that it's all up to you on Christmas Day it can get very exhausting.
For instance. My mother-in-law has all her family round, 7 children plus their partners and around 12 grandchildren, not to mention cousins, aunts, uncles etc. They come in droves on Christmas Eve, Christmas Day and Boxing Day. She cooks for them all, putting on a buffet in the afternoon and a meal in the evening.
Not one of her children helps her. In fact one of her daughters even brings guests unannounced and then wonders why her mum seems to get upset!
Usually we are there and I spend most of Christmas Day helping her to cook, lay out the table, clean, serve drinks etc whilst everyone else just enjoys themselves. Dh does his bit too, but then he gets caught up in the whole extended family thing and I'm often left in the kitchen on mi tod.
So there is being full of goodwill and there is having the piss royally taken out of you.
However if you only have a couple to cater for then you should stop being so bloody selfish and make their Christmas special. You've had your Christmasses.
