From another forum i'm on..
Friends of friends have a special needs kid, dunno what specifically, but he's almost 20, and ok to be left on his own. Nice kid, loves Harry Potter, all that. Big lad too, and strong
Anyhow, parents were over at the neighbour's house, and get a call from the kid saying "I GOT THAT GOBLIN". Put it down to his imagination, took no notice. He phones three or four more times same thing, going on about a goblin.
They went home to check - turned out he's seen a midget walking past, run out, bashed him, and locked him in the shed - had him in there for four hours. Midget was very understanding about it all.
