Tonight, most people won't get much peace around dinner time. They'll be up and down answering the knocks at the door from those who are heading around the neighbourhood dressed in Halloween costumes.
It's got awfully fashionable nowadays to take part. You can't even go to the supermarket without being confronted with displays of costumes, hollowed out toy pumpkins and big bags of lollies.
Like Guy Fawkes, taking part in Halloween tends to be a personal choice. Either you are into it, or you're not. Those against will say it's dangerous for kids to be knocking on strangers' doors or that it's just a money-making American holiday that we shouldn't get sucked in to.
Those with children, or who just like to get dressed up, might find it more fascinating and a good laugh.
Like most things, it can be great community fun, so long as people abide by the rules and don't spoil it for others. This year, the police have adopted a very modern approach to spreading the word on the dos and don'ts by producing a video with tips on how to stay safe. You can watch this video on our website.
