You get to buy massive bags of candy, and no one in the grocery store gives you strange looks.
Not any more, but back when I was a kid: Our entire extended circle of friends (about 20 of us) would gather at the house of the kid who lived in the best neighborhood, and go out in groups of five or six, multiple trips. But that wasn’t the best part.
The best part was after the last group of trick-or-treaters straggled back in, we’d all sit in a huge circle in the living room, and the trading would begin. Such glorious chaos! It made the NYSE floor look tame. “I’ve got snickers here!” “How many pieces of gum do you want for them?” “Kitkats to the highest bidder!” “I’ll toss in a pack of Skittles!” All at once, from all twenty of us together, and somehow we made sense of it.
Seeing little kids in their Halloween costumes very cute. 
You are not alone. Except I don’t have any kids, so I get to ignore it.
I have a birthday around this time of year. I tend to plan my birthday party for the weekend after Halloween, because there are too many Halloween parties in my various circles of friends to try to get people together at the right time. I’m not a kid person, so I don’t find kids in costume to be cute. I’m pre-diabetic, so I don’t care about the candy.
It’s in my bottom three holidays.
But don’t let me stop you guys from having fun! Just honor the fact that my porch light is off.
It doesn’t always happen, but I live to see who has the best Hallowe’en costume of the kids who come to the door. A few years back, a young boy shows up with a skull for a face and a huge black cowl atop a black cassock. So far, so good. I give him candy and he says Thank you, and squeezes something in his hand and then THE SKULL BLEEDS!! That is sick, I love it! I howl at him, giving him an additional piece of candy.
I’m crazy for pumpkin anything. Gelato, oatmeal, coffee, anything.
I’m really into the cheese factor. The macabre becomes funny because it’s also a kids’ holiday.
That since I don’t have kids I can just ignore the whole thing entirely.
Costume update:
We had an insane, possibly killer, clown, but the best was definitely the giant, diner-type, squeeze mustard bottle. Other kids were talking about it when they came to the door later. Made my night.
