Because apparantly it isnt U for him to expect that.
On a related note, AIBU to answer "no idea, there is the usual in the freezer"? cos it appeared from his face and slightly snotty attitude that I am.
On a further related note AIBU to wonder why it is assumed that I will make sure that the kids are fed and everything is sorted for bed, even if they arent actually in bed, when he just goes out?
Another related note, AIBU to not expect a slightly sniffy "oh, ok then" when i announce I have a meeting that will be over school run time on his day off (the day we agreed he does childcare so I can work a full day)? Presumably this is because I have been back in time to pick them up for the last 2 weeks.
