Trick!
It's All Hallows' Eve. The night before All Saints' Day.
The evening when children come to the door, expecting sweets to be doled out for nothing more than a half-arsed attempt at dressing as a witch, a vampire or, for the better prepared, donning a skeleton costume bought off Amazon. Thank you, America.
I arrived home from work not five minutes before the first of the bastards came a'knocking at the door. (grumpy)
Not one of them would know what the hell to do if challenged to trick!
though.
