E is for entropy, and the second law of thermodynamics,

a law is a scientific principle that has been proven through and through,

the closest thing that science has to saying "this is absolutely true."

entropy is such a law, and it happily states,

Everything in the universe moves from ordered to disordered states.

It is why a hot plate of dinner will quickly cool to the touch,

and, maybe, why your mother is often stressed so much.

For perhaps another way of explaining this theory,

is also a way of telling you what makes mothers sometimes dreary –

whenever you clean your room you will have to clean it again,

for soon it will be as dirty as when you did begin.
