I unexpectedly got Halloween off this year. What does someone in their twenties do on Halloween?

My mom always hated teenagers that trick-or-treated. A lot of them didn’t even have the decency to wear costumes. They’d just come to the door and demand candy. I assume most teenagers did that, then went to a stranger’s house and trashed it while they got drunk, then woke up in bed with another stranger. I wouldn’t actually know, since I wasn’t cool enough to participate in such things.

So, what do you people do for Halloween?
