Well, I'm not a human, or a deer, or a fish, or a tree - oak, pine, larch, aspen, maple, birch... - I'm not a hyena or a troll or a bandersnatch, I'm not a shrew, or a vegetable, or a rock, or a slug, or a lizard or a bird or a bat. Or a wombat. Oh! Or a hallucination.

I'm kinda running out of things I haven't already learned I'm not, so I think I'm probably the thing that someone said I am.
