To calculate her ratio
of finite faults to love
divide her disappointments by
those days she fell short of
perfection by the width of hair.

Now multiply that care
she sacrificed in staunch supply
subtracting all you owe
and factoring those times she kept
protecting as you slept.

She taught you powers in degrees
beyond your A B Cs.
No variable devotions shown
across the years you've grown
since once she added you to Earth.

So, tell me, son: what is that worth?
