The Wall

There's a wall between you and I.
It's made out of the thickest of concrete and the hardest of rock. It's monumentally tall, towering over everyone around us. It's impenetrable.
And yet we still send out our armies, determined to do some damage. They scream their battle cries. They shoot their cannon balls. Both sides receive permanent damage. Both sides will never be the same.
The war rages on, getting more violent by the day.
Why do we fight like this? Let's take the whole wall down, let's climb to the top. We could be allies so powerful we could conquer the world. We both know this is true.
But we still scream our battle cries, still shoot our cannon balls, and the war will forever rage on.
The great war fought over the wall between us.
