I have my equations, that tell me that I look straight from where I'm standing, I should see the sun rise in the morning, that never ever matches the observed data.

I like my equations, so I call the difference the wall in front of my face.

You probably shouldn't call it 'wall', it is easy to mistake it for wall[0] (I did it first too).
