I was thinking you probably had a reason for not enjoying Halloween. Yes, a carload of teenagers from outside your neighborhood is a good reason for your feelings. What a shame that they can ruin the fun for the neighborhood children. I understand how you feel.
Now, every year, more and more people leave their porchlight out (the local signal for "don't stop here"). It's a shame, but I can't blame anyone for going that route after the mess things have become.
Didn't this used to be about the kids in the neighborhood?
