Officialy time for trick or treating??

[ScaldedCat]

Scalded Cat, in the US you are not supposed to knock on doors if the porch lights are not on. You are only supposed to knock on doors with the porch lights on. Basically the light means you are invited to knock and get a treat. Some still knock on doors with lights out which is just plainly stupid and annoying.

Here they knock on every door in a street, porch lights are not the norm on every house so people just pretend to not be in, turn the lights off, turn the tv volume down etc.
Unfortunately it is not uncommon for kids to put dog dirt through peoples letter boxes or throw eggs at your house if you don't give them anything.
Many elderly and vulnerable people feel threatened at this time of year and there is a spate of burglaries and petty theiving that the police tie in to trick or treating also.
Sometimes kids, or teens more commonly don't even bother dressing up and still expect to be given handouts.
