Are there any actual cases of children being harmed as a result of Trick or Treating? I think any stories that we've heard are purely apocryphal - but maybe I'm wrong.
As Spidey says though - bothering people unnecessarily is far more of a problem. I know that my mother sits in the dark on Halloween night rather than having to get up every five minutes to answer the door.
Personally, I really can't be doing with these sort of things - that goes for Penny-for-the-guy, carol singers, Jehovah's Witnesses, people selling stuff door to door or anything else that means having to go to the front door.
Just as I got into bed last night, some idiots nearby started to set of fireworks. Thankfully it didn't last too long.
Basically I'm saying that I don't care what the rest of the world does as long as it doesn't bother me.
