The eye is the door to the soul.  You can see anyone's soul by looking into their eye.  If there is a small glowing orb thing, they must be happy.  If there isn't a small glowing orb thing, they must be sad.  If you can't see the bottom of their eyeball, that means they're making some sort of facial expression, which would most likely be happiness.  If you can't see the top of their eyeball, that means they probably aren't trying to make a facial expression, which would most likely indicate tiredness or sadness.  You can see a lot of things when you look into someone's eye.

But it's hard to do that when someone has two eyes.  That makes them a freak.  Everyone is scared of them.  If they have two eyes, does that mean they have two souls?
