For me, it's like those identity parades where a presumed witness is asked to point out the presumed guilty person. I'm trying to find out if I'm the same person I think I am. Which means, I suppose, the one I WAS. When? Yesterday? 20 years ago? Or much much further back? Am I guilty of nostalgia? Choosing a time when I was "really" me, as opposed to the more-or-less me whose selfie you're now seeing? It's a puzzle.
I used to paint a self-portrait nearly every year - much better kind of selfie, commonly practiced by the A-list (just noticed that A-list sound like Elites - ha!) of artists through the centuries.
That's about all I have to say on this subject for now. What do you think, if anything, about photos of yourself, taken by you or anyone else?
