I grew up in London near Heathrow Airport and as a child I knew, for a fact, that there was a werewolf living in the tiny space between my shed and my garden fence. I wasn't too afraid of him.... except for every evening at 6pm when a concorde would fly overhead.
I was mainly afraid that no one would hear me scream if he came out and got me.
