YANBU! I always enjoy Christmas with my family, but I've had a few with my dh's family which made me think I'd rather be anywhere else!!
One that springs to mind is when they arrived on Christmas Day, barely bothering to say hello to me or my dh, went straight to the dc's + spent the next 3 days proceeding to hype our dc's up beyond belief! It happened particularly at bathtime, bedtime + mealtimes + our two get overexcited enough about Christmas as it is! I had constant comments from SIL like, "If you can't cope send them to us anytime, we'll sort them out", "You look tired, is it all too much for you?" Thought that was a bit rich considering she was hyping them up! Our ds is autistic, + he was having screaming meltdowns through sheer overstimulation, two of the three of my in-laws were constantly racing around, up + down stairs, producing yet more presents, (ie. complicated lego kits) at silly times like 8 pm when I was trying to settle the children down.
Friends of ours were supposed to be coming Boxing Day + my dh mentioned that they both had colds but would like to come + see us all for a little while. My SIL + FIL started ranting, "We don't want to catch colds, you must put them off!!" I didn't feel we could so said they could come anyway. My in-laws weren't rude exactly but didn't have that much to say to them.
The last straw came on the last morning, when my SIL was energetically bouncing our dd on her knee while drinking tea. Needless to say, tea went everywhere, (not on our dd luckily), but over two new Xmas books, some cards + magazines).
Was so relieved when they left, arghh! The following year I insisted we spend Christmas just the four of us, popped into my parents for a meal on Boxing Day. That Christmas was lovely!!
