I'm not sure it was a hobby or simple boredom. I was grounded a lot and often stuck in the bedroom I shared with my little sister. We didn't have a TV in our room, just my old plastic Sears clamshell record player for entertainment. I put together jigsaw puzzles and since the selection we had was kind of slim I would resort to putting them together on the wrong side...with the cardboard backing side up. I suppose it was great preparation for 50 years later being stuck in the house for days/weeks/months on end with little to do. Most likely I was nearly as prepared for this pandemic as someone who spent years in solitary.
