DSis got married and had a family before me and therefore began hosting Christmas for both my parents and her PIL. I used to go along to but when I got married and had my DD this became impractical (they live an hour?s drive away and we don?t have a car). Also, I hate to say it, but I never really enjoyed going because my sister is very bossy and does a good job of making you feel unwelcome even though she?s the one who has invited you over.
This year my parents were planning to go to hers as usual. However, DMum and Dsis had a huge falling out and have vowed never to speak again (could be a whole other thread). I am trying to stay out of it, as far as I can. But, as my parents only live ten minutes away from me and I was worried they?d have a thoroughly miserable Christmas on their own, I sweet talked DH into agreeing to invite them to ours for lunch. They both said no, out of hand, without even thinking about it 
AIBU to be miffed that they didn?t stop to consider that I might be disappointed not to get the chance to host Christmas lunch for once? So much pussyfooting goes on to please my sister, I feel like they forget I have feelings too.
