Four Minus One is Three

We always build from the ground up.

Never from the sides,

Nor from the top.

For, if we went that route,

It is more difficult to have a good foundation.

It is more difficult to establish anything

And everything

will eventually topple over,

causing an explosion equivalent to

a miscalculation amidst the physics.

But one wrong digit,

and the whole thing falls apart,

crumbling to the ground.

Deteriorating, maybe unknowingly, already.

We think we have everything right the first time around,

And then we look,

check the math,

draw the lines again,

type in the numbers,

and there it is:

Four minus one is

Three.
