I am human, or at least, I pass for one, and I am legally an adult (but don't expect me to act like a grown-up). I live somewhere on Earth, and am descended from a long line of mammals.
Since I created this pen name, I have realized that there already is a "D Porter." We are not related. (Well, if you go back far enough, I'm sure we have ancestors in common, but you know what I mean.)
