People are getting more boring each day....that's not funny anymore :(

I think being direct is nice. I wouldn't be upset if some kids came to my house and said that

I once said that I didn't have any candy but if they wanted I could give them chocolate. They had a little discussion among each other and concluded that their mum didn't rule out chocolate with nuts. I replied it was dark chocolate and a no nonsense chocolate without milk, sugar, nuts, honey, almonds or such. They were sad. Then I found a tiny package with fruit gums from the plane I did travel with and the sunshine appeared back in their tiny faces. I would have had bad feelings otherwise.

IMHO it's against the rules, but it's understandable. You don't want to put people on the spot who aren't giving out candy.

Maybe tricks are cancelled?

Hm, I can't say I've heard that, I don't what the rules are anymore, or if there even are any rules, but if it's politeness people are concerned with, then where is the 'please?' personally for Halloween I'd go the other way, all like 'FOOLISH MORTAL, I HAVE COME FOR YOUR SOUL! But I'll take those peanut butter cups instead'

Nah, only tricks here.

Kids are getting lazier nowadays so it's easier to just ask if they have candy or not.
