So, trick or treat etc.

[Burney]

I won't open the door.

I've hated it since the moment in 1992 when a small Pakistani child came to my door in Leeds while I was horribly stoned and shouted 'Trick or Treat!'

Completely panicked, I gave him my flatmate's box of Shredded Wheat, shut the door and refused to open the door for the rest of the night.
