So, myself and my siblings (all adults in 30s) alternate Christmas day between our parents and our respective DP's parents. Thus, we have a big family christmas every two years. This year, my DM has asked us (me and DP) not to come because her dogs (two young dogs that have replaced now deceased family dogs) are nervous of my dog. Not only that, she was upset when I suggested we might have siblings and neice here on boxing day to compensate. My view was the dogs would just be expected to all muddle through for 48 hours for the sake of family. My dog is a great dane but very placid and uninterested in their smaller dogs. We'd also have been quite amenable to confining him to the utilty room but no such compromises were sough, just 'we'll miss and its a sad situation'. So, AIBU for being upset that my mother would choose her dogs over her child?
