I don't mind the neighbours kids coming round to show us their scary outfits, my own daughter does the same, but I make a point of having sweet treats rather than handing out loose change on the doorstep.
As the nights draws on some of the bigger kids come round looking to seize on the chance of some extra cash and I make a special effort to save a few extra-dainty kiddy-sweets for them. But first I make them mumble the obligatory rhyme.......
Head down, feeling rather silly ..."The sky is blue......."

C-flat.
