When you think about it long enough, Valentine's Day is really random. And by long enough I mean at all, and by Valentine's Day I mean also St. Patrick's Day, Arbor Day, Fourth of July, Veteran's Day, Thanksgiving and pretty much every holiday that is not Halloween.
Halloween is a day of self-reflection and inner soul searching, a time that brings the community together, that really reflects what this country stands on, completely identifies us as a people of deep moral purpose and enthusiasm, encompasses what the other holidays lack: fake blood and finally getting to take candy from strangers.
