DH has just come home from work in a foul mood basically because I told his mother I was taking a lieu day off tomorrow (having worked the last 2 bank hols)and she has had a wobbler about it 'cos I should take them off when it suits her and when it's useful presumably. I told DH it was none of his mothers' business when I take my annual leave and since I have another 4 weeks owing it's not likely to be a prob if his mum wants to drop out of childcare and we need cover (of course he can NEVER rearrange his work)but he seems to disagree and think she should call the shots. AIBU???
