Practicality: Do You Believe?

Discovered fire with 2 stones

And the bed on which you groan

Good they kept and evil was thrown

So behave or you're gone

Learning by yourself was prominent

And if you've learned it was evident

Practicality is what they believe

And now to its loss the grieve

Now it's time to throw books out

Bring Practicality in the house

Theory seems nice

But

Practicals are better

It's like reading wind or facing its tremors

So let's help to bring in the change

Or

Practicality would be out of range!
