I can relate. I had one tenant who was an absolutely helpless, royal PIA. At least four times while she lived there, I had to drive over to show her how to reset a tripped GFCI outlet in the bathroom or flip a breaker. (Showing her once wasn't enough.) Twice I ran over to fix a window that "wouldn't latch" and had to explain to her like a child that was because the top sash had slid down 1/2" and she just needed to push it back up. Then there was a bee's nest on the shed that shed that she didn't use. When I suggested hitting it with some bee spray, she said she was too scared to do that, so that was another trip over. When the ice maker "wouldn't work", I had to show her that was because the ice cubes had frozen together in the ice hopper and all she needed to do is run some water in it in the sink, dump out the caked ice, and put the hopper back in the freezer. She couldn't even figure out how to use a plunger to unclog a toilet, so I got to take care of that as well. When she complained about the smoke detector chirping, rather than show her how to change the battery, since she'd apparently never done in her life, I just installed a new 10-year lithium battery smoke detector. But then the next call was her complaining that the new smoke detector had a green LED that stayed on all the time and kept her awake a night. That's how insufferable she was.
For a while, I was getting calls weekly about something that was "wrong" in the house because she was a complete idiot. It was ridiculous. I honestly don't know how she even wiped her own ass. She'd left her husband, who is a super nice guy and fishing buddy of mine (which is how we wound up with her), and yet HE was the one paying the rent, while she didn't work at all, which made no sense to me at first until I realized he was probably more than happy to pay it just to get rid of her. When she suddenly decided to break the lease early before her first year was up to move in with a new sugar daddy she'd just met who was 20 years her senior, we didn't contest it at all. We were both like, "Good riddance!" While fishing one day, her ex acknowledged that she was a nut job and actually thanked me for putting up with her BS, and said the only reason he had stayed in the relationship was for their kids' sake. That dude is a saint. Oddly enough, the current tenants in that house don't seem to have any of those problems.
