My mom and I have a warm, close relationship built on love and mutual respect... and I'd really like to highlight the love and respect, as I'm about to playfully drag her. Because my mom is, like all moms, a human. And like all humans, sometimes she did stuff that was just weird or inexplicable or nonsensical. But when I bring up those peccadilloes insofar as they relate to my childhood, she "doesn't remember." Suuuuuure. So here are things from your childhood your mom pretends never happened, at least based on my experiences with my mom.
Another aspect of all this is, I'm sure, plausible deniability. You see, my mom raised us in the '80s and '90s and the things that were totally standard in the '80s and '90s are just no longer... what's the word... legal. (What can I say? It was like the wild west, folks.) Or at least those things are no longer considered to be a "best practice."
But you know what, you guys? In 20 years our kids are going to be horrified by the things we did to keep them safe and happy and well-balanced and we'll probably turn around, look them straight in the eye, and say, "What? That never happened. What are you talking about?" So here's to continuing the cycle of amnesia, one misremembered moment at a time.
