I wonder if you'll feel the same way when you're older and a person in that photo you didn't take no longer has the capacity to remember the event. Or they're dead and you're talking to a loved one about something you learned about them on that trip.

I have found troves of photos taken by my parents. I distinctly remember being impatient about being in them (and I'm not in most of them, because of that). But it's a tremendous gift for me to be able to send them to the people that are in them that are still alive, so they can remember the ones who are gone. Or just remember the moment that is long forgotten by all of us.
