I have to correct this because it annoys me a bit.
Humans ARE animals.
You mean you want to be a different species of animal, or you want to be a combination of two animals. (human + other animal)
I know, I'm picky, but it ticks me off when people say "I dun wanna be human, I wanna be animal!"
You. Are. One. Already. Damn it.
Not directed entirely towards you, but to everyone who says that. I'm not trying to be mean here.
Anyway, I have wished I could be another animal. I'd like to see what it's like as a bear, or lynx, or rat, or any creature. Hell, I'd like to know what it's like to be a tree. It would be cool to see life from a non-human's eyes. But I do think it's best to stay human. It's the species I was born as, and I will stay as that until the end of my life, and who knows what's there? Maybe there is when we can finally see what life is like as another animal. I'm not sure if that will happen, but we'll just have to wait and see for ourselves.
