I sat at a table with a deck of cards and played solitaire.
as long as it wasn't a deck of 51
Played grabass with my ex wife as she wasn't an ex then!
I'm very fortunate that I'm never bored. But I used to find time to read, play the piano, and work part time.
I spent a lot of time reading ... still do, actually.
I did wank a lot.
Read books. I checked out about 5 books/day from the local library. LOL
Games. Board games, card games, dice games. Whatever I could get a group together for.
Legos. LOTS of Lego building with other kids in the neighborhood. We all shared kits, and took home what we built and an even split (by "pile") of the leftover pieces. LOL
Computer games. Yep. Early computer games didn't require the internet. Imagine that.
I would just watch TV or play with my GameCube.. go for walks and bike rides.
Well I had friends back then, so whatever they were doing like 80% of the time.
Never could be bored with a book in my hand.
