My house is a complete shit tip. Have felt totally zonked this weekend so hardly done anything. Dh has been an arse and was stropping earlier that there's shit everywhere, maybe he's worked out that the only reason there's normally NOT shit everywherenis because I clear it up (he has made me roast lamb today, but even so, he's been an arse). I'm about to attack a tub of choclate ice creM.
poly we alternate between Christmas at my parents in the UK (with dsis1, dbil and dbro, and dsis2 if she's in the country) and Christmas here where we go to ils for coffe in the morning then to ours late faternoon for dinner. (They are our ndn so easy to see them for part of the day and have a break). DBIL and DSIL are always unavailable for Christmas, we have never been invited to theirs and lastvyear when we were in the uk they wouldn't invite PILs over so they spent the day on their own 
Will prob do the same this year, but dh will cook anyway and I will be firmly ensconced on the sofa for the whole day. My DPs are heading out to visit on thd 31st for a few days but not staying with us. They'll either have a lovely newborn to coo iver or they'll be taking ds out for the day (perhaps both!).
poly I would make clear to everyone now not to expect an invite. If you get invited somewhere else and you want to go fine, but if not then enjoy a Christmas with just the 4 of you.
