Aged 12 in a English lesson in the mid 90s, I wrote a poem about a lost cat. In this poem I used the line, "I wonder where my pussy is?" Completely innocently. I was a sheltered 12yo in pre-internet times.
I took my work to my male teacher to be read. Then he asked me if I'd ever seen the tv show "Are You Being Served?" I'd never heard of it, shrugged and said no, and the conversation moved on.
It was only as an adult that I became aware of one of that show's poor jokes was people mis-understanding the use of the word "pussy" and making innuendoes.
ERGHHHH!
The thing is, 12yo me remembered that exchange with my teacher and how it felt weird and out of place. Some part of 12yo me knew it was wrong. And it was only when I was about 30 I realised just how gross it was.
Another time, I don't remember exactly how old I was, somewhere between 9 and 11, I got a pair of roller blades.
I was still getting used to them, and was out in them on a stretch of path about 30 seconds from my front door, but out of view. I happened to be wearing a skirt that day, and at one point I bent over to adjust the strap on one of them.
While I was bent over fiddling, this older man came up from behind me, and said something like, "oh, that looks fun" and then walked off. But something about the way he said it made me uncomfortable. Then I realised I'd been totally flashing my knickers. I hadn't just been bent over for a few seconds, but maybe half a minute or more, so he'd got an eyeful of practically my entire backside.
It wasn't so much what he said, and it may have been entirely innocent, but it gave me he heebiejeebies.
I never reported either of these events, just shrugged. But looking back at the first one, especially now I'm a teacher myself, it was just so wildly inappropriate, it would never pass nowadays.
