I was away for a short trip and gave mum's DP and friend permission and instructions to borrow a motor scooter for a holiday event. They did not follow any instructions and removed the vehicle prior to the event because it would be easier for them. A medical emergency came about, and the scooter ended up in (safe) storage. This issue is that the vehicle was not there for me when I got home, nor was it available to other people to use for follow up activities. (also given permission). I didn't know where it was, where the keys were, how to get into the storage unit when I found it, and if the battery was dead from being stored in the cold. I was pretty upset, but didn't address the issue until I returned home. I enlisted a friend to help retrieve the vehicle and began to inquire where it was. DP and friend had no idea it was a big deal, but i was pretty mad. I firmly told them the vehicle needed to be home. At this point, they got the hint and showed up at my house with the vehicle after I made a point to tell them to leave me alone. I got pretty hot when they showed up and let loose in a tirade. Now my mum insists that I apologize for the outburst. I don't feel an apology is warranted, as I was in my own home and asked to be left alone (because I was already mad). I am not allowed to go to their home for the holidays or to visit for other occasions, including family gatherings. She said I must be "disciplined" in defense of DP. I am over 50 years old, and I've had enough of my mom's repetitive crazy demands. I'm not even sure what to apologize for, and words like "discipline" continue to widen the existing gap between us.
