The Halloween is for the children. They're very enthusiastic and excited about the whole thing, so if ppl decided to take part of it, decorated their homes to expect the visits I do agree they should at least be in a good mood and yes, smile because it's just the poor kids having a great time!
Nobody has yet answered the question that I and others have asked: why does decorating your home for Hallowe'en automatically mean that you welcome trick or treaters with open arms?
Why does it have to be 'you must celebrate Hallowe'en in the way that I dictate or you aren't allowed to celebrate it at all'?
People have already said that they have year-round general decorations on their house, and trick or treaters have decided they must be pumpkins or whatever and thus they are entitled to knock. Presumably, you're expected to UNdecorate your house for a week if you don't want trick or treaters?!
Also, what's the betting that people in some areas will be criticised if they don't 'get in the spirit of it' - like the people who were 'shamed' if they didn't go out and bang saucepans 'for the NHS' for whatever reason?
Rather than rely on your own personal interpretation of subtle arbitrary indications - like the old having an aspidistra in your front window to supposedly signify that you're middle-class - Surely the best way would be for participating houses to have signs up saying "Trick or Treaters welcome here!" It can't be beyond the wit of Poundland to start producing these for those who want them. That way it's unequivocal and everybody knows the score: see a sign, visit and get sweets; no sign, stay away.
