There it was, just where I had left it. I gently picked it up and put it my backpack.
Taking it out now, I see it looks different in the daylight. Up close, it no longer looks like a heart but just a folded receipt with a couple of worn spots and a yellow stain. I don't want to alter it, but I am curious as to its origin, so I carefully unwrap it. No name, no store name. Just a to-go order of tea purchased at 7:10 p.m. the night before I happened upon it. I carefully wrap it back up.
Another day, another heart preserved.
