I don't know if it was like this for you, but when I was a kid, I lived in a building where old dudes from all over the place would gather in the yard. There was a table where they'd sit and play dominoes constantly. I know it's kinda weird, but I really feel like that game is just for retirees.
Nah, a lot of people still play. Even now. I've even seen websites to play dominoes online. The only question is whether it's actually fun. For me, not so much. Maybe I'm too young to get the deeper meaning of the game.
