I'm of the firm belief that it's more fun to believe in things like aliens and ghosts than it is to not believe in them. We all have infinite choices of how to live our lives, so I'm choosing to think that the reason my bathroom door swung open is because of a benevolent ghost and not the wind. I don't care if it's rational or not.
Plenty of things aren't rational but are still good. It's not rational to eat as much shredded cheese as I do in one sitting, but I do it anyway. So if you see me putting together a guest room for the alien I'm going to bring home from Area 51, mind your business. People do things that are a lot crazier, like looking at memes all day. Just kidding, that's a perfectly acceptable behavior here at Memebase. So scroll on, brave friend. And beware of the ghosts.
