I Was 10...
when this was painted.
I didn't see it until I was 25.
It took me slightly longer to begin to know what it meant, truthfully, and not as some childrens' game.
I see new things in it (the painting and the words) all the time, about people I know and people I don't, or don't anymore.
All of this is for better and worse simultaneously, which is what makes it (the painting, the words, the idea) alive, I think.
