Lesson

Someone's loss is some other's gain
Give a cat a diamond is an attempt in vain
But your leftovers will ease its pain

You saw the sand when you stepped upon
Someone might see glistening silicon
You can't see what you'd rely on

The stone that you threw away
Can be the one you crave someday

What you give you'd get back
But the card you put in the sack
Won't come back into the deck

Yesterday when you made a mistake
Is a lesson for you to take

Today is to be cautious
Before you lose another precious

If you walk the same path
You'll face the same wrath
It's the simplest of life's math
