Basically my ddad died 10 years ago. Since then Xmas day has ALWAYS been just my siblings and I and mum even now we are all "grown up" it's my favourite day of the year, pretty much the only time we get "just us" as a family. It can be a slightly hard time especially for mum, as they adored each other. As such we don't really rock the boat on the day.
A good friend of mine from school (so known her for around 15 years) mum moved abroad this year and she can't afford to go, her dad lives nearby but she doesn't want to go cause she doesn't want to spend Xmas with her step mum who "nags" because she is messy (she is)
She's asked if she can come to ours for the day (would be my mums house), Aibu just say no?
I'm worried it's mean but it's another person to cater for and tidy up after, and it messes with tradition we've all enjoyed for a decade.
