DP leaves for work at 6 am. The week before Christmas his company do some fundraising for charity which is aimed at children (I.e. there's a Santa involved) and DP says he has to do this, it is not optional. This means for the full five working days before Christmas eve he's out from 6 am - 10 pm and I'm left doing nativities, parties, presents, wrapping etc with four DC in tow and he's knackered for Christmas. Aibu to think he just likes the social side of it and can't be forced into working 16 hour days with no financial reward?
