Not an airline pilot but still being an instructor I don't fly for fun very much either.
To me it's like a gynecologist going home and looking at vaginas recreationally. Hmm ok bad example.
How about a cashier going home after work and playing around with a toy till?
Same with flight simulator. I used to love MSFS until i realized i just spent all day doing this for work...Why do it in my off time? i guess flying is kind of different though than reproductive organs and cash registers. Still more work than recreation for me though.
