I don't do so well.
During my late brother-in-law's last illness, friends took a full size picture of him ("flat Chris") and photographed it in places he'd been or wanted to go and sent them to him. Some were posted on Facebook and I saw them too, in places I also used to visit. Even the places I'd been to many times I barely recognized.
The building with the physics and math offices at SIU-- still there, still the same--I didn't recognize the facade at all. Visual memories seem to go in a dust blender in my mind, and all that's left are fragments of a view here or there associated with some dramatic incident.
I would sometimes see a student walking down the street and think "That looks like X from my high school." When I last looked at a high school yearbook I didn't recognize half the faces anymore, even though I remember interactions with them, or the look in her eye, and sometimes even the conversation.
I must file all that sort of thing in medium term memory, and reuse the space when its been idle too long. Or something.
