Recently I've been witnessing a change within me. I'm not surprised; I've always been one to shed dead skin, almost like a snake. I will slither onwards to seek my next prey. Outsiders won't find me. Insiders will have a little trouble understanding me. Of course, this isn't a goodbye, but it is still a goodbye nevertheless. Think of it as a goodbye from the "past" me.
Snakes will always shed their old skin. My taste in prey has slightly changed. The venom in my teeth has aged just a tiny bit, I'd say.
