I was thinking the other day about how in my 80s childhood that we were taught to avoid "dirty old men". Like nobody did anything about men preying on children, they just told you to avoid them. We had a neighbour growing up who had lost his teaching job for exposing himself to his students, and he also exposed himself to several other people in the neighbourhood, and did a lot of other creepy antisocial things (like abduct my cat and dump her outside of town, or put a sandwich bag over her head), and yet I was sent to piano lessons with his wife, where sometimes he would wander into the room in his underwear. If that was someone today he'd be on a sex offender list and in jail, but my parents thought it would be rude not to send me there for lessons.
We also had a guy who roamed around naked in the woodlot behind the grade school. I thought it was an urban legend and then I saw him myself one day when I was crossing the bridge overhead.
