Hallowe'en is dumb
IMO The only dumb thing about Hallowe'en is the dressing-up part, but it's fun. It's the only time of the year you can walk up to every doorstep in your neighborhood and get candy for just showing up.
Then the next day involves you and your siblings/roommates/etc. on a massive sugar high. Fun stuff.
I might be in jail on Halloween.
Stop dressing up as a local serial killer, then.
