I like to go through a cemetery near where I work when on my lunchtime walk. Why? Cemeteries are beautiful. Peaceful. Empty (of the living).
I always find something new.
One week, I saw a marker that had a baseball beside it. The next week it had another. Every time I went back, there were more.
A month later, a vase appeared and the baseballs moved inside.
Adjacent to the cemetery, sharing land that was gifted to the city, is a varsity baseball diamond for a high school team.
It would seem that a lot of home runs sail out of that park. And, unlike in most cases, no one retrieved them.
I imagine someone coming to pay their respects to the deceased and seeing a baseball resting nearby. Perhaps their loved one was a baseball fan, so they placed the ball by the marker, said their well wishes, she'd a tear or more, and left.
After that, it just became "the thing" to do. Each time a home run left the diamond, it landed nearby and then became part of the permanent memorial. Maybe by the same visitor or another who saw what was happening and kept it going.
Whatever the case, it's cool. And one of the places I like to visit. If I find a loose ball, yeah, I'll likely add it.
