Maybe that lady was playing with her phone in the laundry room, or exited the building to smoke or something? I'm glad that you found some good in her despite the bad experience… you are a good person Bobby

Let the housekeeper you like know about your bad experience with the other lady, and explain that that's why your apartment isn't as clean as you would like rather than pushing yourself too hard trying to make up for her laziness.

The arthritis in the leg that wasn't effected by the stroke may be acting up more because it was compensating for the one that was. I hope the pain does improve
