One of the perks of advanced age is all your elementary, high school and college teachers have likely passed or could not pick you out of a school picture without the caption and your former classmates have trouble remembering what they ate for lunch.
I don't know... :-) I've run into a few high school friends who say, "Remember that time..." About things they insist happened almost 40 years ago. Their memories aren't perfect, but they're always convinced this or that happened exactly as they remember.
