My wife is still like that. When we travel, she goes around with alcohol wipes and wipes stuff down. She learned very quickly she shouldn't do that to exterior door handles as it destroys the finish on the door handles leaving them looking very rusted. Though it took her 4 times before realizing she was destroying the door handles.

I got into a period of separation (with divorce thrown into the conversation) after getting in an argument on why I don't wear masks anymore. Since it negatively impacts the kids, I got wiser and put on a mask when I am around her and find excuses to take them off (like drinking water and never putting mask back on).
