It counts enough for them, at least; they gather up in front of the door before the tallest one reaches up and rings it. There's a slight pause before the door opens and a young woman steps out with a bowl full of candy to the loud chorus of "TRICK OR TREAT" from the three children. All three reach into the bowl and pick out something, stuffing the candy into pockets of their costumes before sprinting across the lawn, waving and yelling thank-yous to the lady on the porch.
