My mum told me that a girl fell off the bus station roof (we lived very close to it) and broke every bone in her body, and had them all reset without anaesthetic, obviously to discourage me from climbing up there.
I don’t know why, I didn’t even climb trees, never mind bus station roofs.
Not my parents, but my brother told me that all the skeletons in the graveyard opposite our house would climb out if their graves and get me. That one did terrify me! 😂
