No, no, no. You don't just look alive.

But...

Hee...?

I figured you looked pretty pale, but a corpse?

Well. I suppose I look pretty lifelike.

You also have all these little gestures and behaviors.

Not to mention... I doubt you'd go out of your way to fake diarrhea. You get thirsty and hungry, so clearly your insides work too.

Looking at it that way, you're as human as it gets.
