I guess this is more like an AIBU, but I don't want to set myself for a flaming, so am unloading here..
I'm one of three, and have quite a difficult relationship with my mother. I knew she was going into hospital for the day for an operation on a shoulder ligament earlier this month, then she told me it was postponed until January. My sister contacted me to tell me that she had it yesterday (and it went well, thankfully). She and my brother are sorting out microwave meals for her and my dad, but I just feel 'why should I bother' if i'm not kept in the picture about when she has it done.
