Everyone is a freak in one way or another, and some in more ways than others. No, you don't have to be Marilyn Manson to read this.
It's only common that one's freakiness is detectable and scrutinized by everyone but him/herself. That's because what everyone else might consider queer falls in the scope of normality for that one person who exercises it. The whole thing is simply a difference of opinion.
Nail-bitters were once considered psychos. Of course that was before toenail-bitters came along. It's typical or even beneficial for certain animals to consume their own poop but intolerable for children to occasionally have a taste of their booger. But really, which one is nastier?
I once knew of a cola freak who only drank freshly-opened refrigerated canned Coca Cola poured into a glass with four cubes of 2oz ice cubes, and a toothpaste freak who would make the effort to force the toothpaste up to where she thinks it belongs after other members of the household have been squeezing toothpaste from the middle instead of the bottom of the tub.
Okay, that was me.
In my opinion, if you're going to be a freak, you might as well be a unique one. Pick something that's distinctive, something that makes you stand out in a crowd, something that makes people point fingers at you and murmur behind your back. Try chewing on someone else's straw for a change.
