I started seeing this song as a way of socially distancing from people who are infected. Even before covid, because the world was telling us non-stop about how every flu strain was going to kill us, including young and healthy people, and SARS, which covid is a novel strain of, and at the beginning of Covid I was sure there were going to be dead bodies in the streets and the local hockey arena would be turned a morgue and mass graves would have to be dug. Avoiding the disease no matter what did seemed impossible, and one night I flew into a rage so bad the landlord called my mother and she talked to me afterwards and I was scared to death of being kicked out of my apartment. It's kind of surprising how quickly I adjusted, though. But the world will never be the same again and any minute now there might not even be a world left.
But I digress. I used to hear that song for years and had no idea it was supposed to be about a teacher who is attracted to or having a relationship with an underage girl in his class, or something creepy like that. I feel bad sometimes for not reading between the lines. My brother use to make fun of me for not understanding the hidden "deep meaning" of a song or a poem.
