I want to just have Christmas just with my own family and people I want around. My sister unfortunately I don't get on well with an no one wants her around, just brings a bad atmosphere with her. Without sounding like a bitch, its probably her own fault that her marriage broke down and she has no friends to spend Christmas with. Her attitude and the way she treats people is exactly why.
Aibu to not invite her? She probably will have a few pity invites and mine would just be another.
