with this american holiday comming up really like this

but have few questions
how many brits celebrate this surly its normall now im going to party myself still unsure of constume and my kids love to dress up and trick or treat

how did this come about as lot of americans hear someone can tell me
i mean all year i tell me kids dont go out at dark and dont talk or take sweets off strangers then this day i tell them to seek strangers and ask for sweets
thinking about it its madness


and also who else will be dressing up and what will you be wearing
