I thought the rule was you only knock on doors where there are obvious decorations or lit pumpkins - basically an invitation to come?
We usually do it and have lots of sweets but I just didn’t feel up to it this year. Teen dd has gone out and it’s just me at home. No decorations at all. And some kids have just come knocking. Have now had to turn lights off at the font to make it look like no one is home!
