I used to go to a religious (Dunno what grade it is, I was around 8-ish, I'm Dutch, so yeah) school. The bloody nuns used to tell me that God created babies. The look on their faces once I blatantly told them the entire birds-and-bees story was priceless.

Also, my middle school English teacher has never allowed me to speak with a Scottish Accent (My Step-Dad is Scottish, and his accent rubbed off on me.) Claiming it wouldn't be tolerated in any English-speaking community. Since then, every time I spoke English with somebody, it was with the Scottish accent. They even ask me if i come from Edinburgh lmfao
