I'm glad to have read this, it gives me a little comfort to see that other people deal with same issues. Sometimes I just close the door for her when she's in the restroom.
I feel like a lot of these habits come from having lived alone for a while after leaving home. I have a lot of habits that I'm 100% certain I didn't do growing up because my mom would tell me not to. I would probably have kept them if I had started living with other people later. My mom on the other hand now does the things she used to tell me not to and I can't help but think that it is related to not caring anymore after living in solitude for decades.
