If you're American sure I guess......but it never stops amusing me when Americans think Halloween is some huge holiday outside the USA when it isn't at all in a lot of places. I've never in my adult life had a single person do trick or treating at my house or seen anyone do so. At most there may be a party for some people these days where they dress up and stuff but it's a barely recognised thing here and that's more about just having a get together with others more than anything else. Despite stores trying to turn it into a thing every year to get in on that mass consumer spending train the usa ones are able to get in on. All that seems to happen is they buy a bunch of random chocolate and costumes etc that don't get sold and end up on deep discount every year even before the day is over because no one really buys them. Which is about the only good thing that comes from it, the fact I can buy a bunch of chocolate for discounts because of an attempt to make a manufactured holiday a big thing here.
It also doesn't help Halloween that people outright find the idea of people knocking on your door at night asking for stuff annoying as fuck, kids or otherwise, a lot of people here don't want people banging on their doors at night at any point. Also doesn't help that we have other occasions around the same date that are more widely celebrated here which other places don't celebrate so Halloween is just ignored for the most part and often seen as "an American thing" (origins or not it definitely is a more American thing now) when stores try and make it a huge deal over here. It's been 20+ years since I noticed them trying and it still isn't happening but they won't stop trying.
