I have a small tin box that something or other came in as a gift. It stored concert tickets and other small memorabilia (like the movie ticket from a great first date) for every event I'd gone to for well over a decade.

Gradually, as physical tickets got phased out, I had fewer and fewer items of memorabilia to add. At this point, I have no physical record of shows we see. I feel like something has been lost. But I suspect far fewer people kept these tickets for nostalgia than threw them away, so I guess I'm not mad; I'm just disappointed.
