A name engraved on a park bench means someone wanted a stranger to rest where their person used to.

A bench with a name on it is a quiet piece of generosity. Somebody who lost a person decided the best response was to give strangers a place to sit, in the spot where their person used to sit, and most people who use it will never read the plaque. The gesture asks for nothing. It converts a private loss into something useful to people who will never know the story.

Next time you pass one, read the name. If you ever want to mark something, you might consider the version that is useful to somebody else: a donated book, a thing kept in repair, a seat in the shade.
