When Does an Ordinary Object Become a Milestone?

A key, a ticket, a note tucked into a book: sometimes an ordinary object gathers meaning because we keep it. But the object itself doesn’t explain what it means; the story we connect to it may change, too.

Has an everyday object ever become a marker of a moment in your life? What gives it meaning for you—the moment it came from, the choice it reminds you of, or something else? You can keep the story private; even a few words about the meaning are enough.
