Those rambling on about themselves,
Will not be concern about hearing...
Of another losing a close family member,
Or a beloved pet.
Or could they care any less,
About one's giving up eating...
A missed dessert.
That has icecream and bananas...
Assorted toppings and whipped creram on it.
Or the pronouncing of another's last name,
To get that correct.
Those rambling on about themselves,
Have only one interest.
And it will not take a scientist,
To guess what that interest is!

Lawrence S. Pertillar
