I understand. Perhaps in their own way, they have a level of trust. I could sense by your words that they see you as non-judgemental and unafraid to continue servicing their household. They know that you know the disruptions they live with but is still kind, caring, and willing to assist.
You are right in that those you least expect it from, you kind courtesy and respect. My father-in-law had a home health care worker who always went beyond what was assigned for her to do. She once told us that he was like a grandfather figure with worldly advice for her problems while she worked and helped her financially beyond her employment pay. You don't meet many people like that.
Thanks for your engagement. Take care.
