My mother (who has dementia and needs constant supervision after a recent sharp decline) has this best friend she hadn't seen/talked to in a month or so, so I called the friend yesterday so mom could talk to her. After a few minutes, I got on the phone with the friend to update her on mom's condition - during which she mostly talked over me about her own cognitive problems, the multiple medications she's on, and other health issues. The friend wanted to schedule some time to hang out and became very argumentative and hung up on me when I told her I'm not comfortable with leaving mom under her supervision at this point.
When she and mom hang out, the friend takes my mom around on numerous errands and doesn't stay with her the whole time, which mom finds scary, especially in the crowded big box stores the friend tends to frequent.
I don't feel the least bit comfortable with mom spending time with this friend anymore. I'm legally responsible for my mom now, and though it bothers me that I would have to restrict who mom hangs out with, I don't trust this friend to make sure my mom is safe under her watch.
Before the friend hung up on me, she said she was coming over anyway next Saturday to pick mom up, and I just need to deal with it. I'd prefer not to escalate the situation, but mom's friend tends to make scenes. How do I handle it if the friend shows up to the house demanding to take my mom off with her somewhere?
