I’m curious. If you really wanted to spend a Friday night alone doing your own thing, would the doctor be mad? Is that why you don’t tell her? Nothing wrong with wanting to your own thing once in a blue moon and chill out alone. Putting rules on it is what stinks, lol.
I also enjoy my Friday nights where I drink my wine and watch TV no one else likes with my hair in a mess bun in my PJ’s.
