I too have a ton of books and several games. I would like time to draw and paint- have a lot of art materials- used to teach art to teens. I enjoy reading and like puzzles too and saved a bunch of them from old papers. Being out foraging is fun to me but probably would be work later.
I might like to just do nothing if I had some down time. Sitting around a fire talking is fun if you can make a fire. Kids may actually learn the art of conversation instead of texting. Doing things with kids like spotting different constellations at night or making willow whistles. The list is really endless.
