Quick AIBU, as DH thinks I am being unreasonable whereas I think I have a legitimate right to be pissed off.
Sister works shifts and despite originally having NYE night off has now been told she has to work. The original plan was we would all go to our parents on 30, stay for NYE and leave evening of 1 Jan. whereas now she is getting there on 29, we get there late afternoon 30 and she leaves morn of 31.
I asked if she could swap shifts to work xmas eve night and she said no as she had an old friend coming to stay. When I pulled her up on this she said oh no it's not fair on my kids, but surely if that was the reason then she would have said that, not that a friend was planning to stay.
Then her husband asks (calling my DH about five minutes after sister puts phone down on me) if we can pick him up on our way to our family as he is going to go out with friends on 29 so won't go up with my sister - this will add on about 1 - 1.5 hour onto the journey. At best the journey would have taken 3.5 hours (plus the detour time) if roads clear but last year it took us 5.5 hours. He could drive himself or get a train.
AIBU to be bloody pissed off that sister won't ask to swap shifts due to old friend visiting and brother in law expecting us to detour to pick him up? DH thinks I have no empathy and shouldn't have had a go at her
