Halloween is a holiday where:
You don't have to prepare food.
You don't have to meet up with family.
You don't have to attend a festival.
Halloween songs can be catchy, but they're never repetitive or played for months on end.
It can allow pretty much anyone to partake in it regardless of religion or background.
It's completely voluntary with no peer pressure to do anything or attend specific functions or travel anywhere.
Halloween lets you be, however you want to express yourself, and it's the one night pretty much no-one will judge you.
