Hallow-teen?

What should be the age limit for trick or treating? I think the correct answer is 12. Teenagers are too old for this, but when that something-teen "dressed" as a hobo comes to the door too late, I'll give him his candy and be pleasant about it so that my tires won't be slashed in the morning. Way back when (pretty tired of that "back-in-the-day" thing, aren't you?) we used to grab a pillow case and head out with our friends without a worry. Now, there seems to be almost as many parents out as little ones, who just guardedly cruise the immediate neighborhood with those sad little plastic pumpkins. Halloween is now the number two selling holiday, largely because of those who grew up that still want to play. And that's OK, but the teens and adults should be at their parties, and let the little kids do the trick-or-treating. I miss those days of innocence with the little ones in their homemade costumes, wandering the streets in their raucous way. Now it's a month of hype and the night taken over by teens and adults. Yeah, I'm getting old and sometimes get caught in the old man "Back in my day" thinking, but is Halloween better now? What's so fun about the "fun size?"
