My kids are still quite young so there is still at least one annual trip to the zoo where I feel compelled to take pictures of most of the animals we see. I can honestly say I've never had a moment where I thought I really needed to go back and look at those animals again. Regardless of how adorable the red panda is.
I can't recall that ever happening. Prior to digital cameras, I'd sometimes neglect to get a roll of film developed for a while, and they became a mystery roll. I miss that! I loved picking up photos at Walgreens, Target or wherever I had a coupon for double prints and looking through them! I rarely print my photos now. :( I usually only do if someone specifically asks for an actual printed copy.
Yeah, I love taking and looking at photos. One of my passions!
I have any number of print and slide photos taken on many holidays, events or romances, but the problem is not one of rarely looking at them, but not knowing where and when because most have no identifiers beyond a brief title of overall place or event, and the month and date, on the packets.
I am a bit more thorough now with cataloguing my digital photographs.
