Grumpy Old Man

"Grumpy old man,"
The young man said.
"Indeed you are very wise!
Though your lines on your face
Have grown increasingly dark
And your hair incessantly white.

How ever did you manage 
At such disadvantage 
Do you think it is truly right?
For you to insist 
While you still exist
To ever put up a fight?" 

The old man scratched his head
As he rose up in bed 
"I feared it might injure my health.
Tho Doctors continue 
To care for me through
On account of all of my weath!"

"Grumpy old man,"
The young man said
"Again you are blind as a bat!
And yet you manage 
To easily walk down the street
How ever can one explain that?"

"In my youth,"
The old man replied. 
"Through every argument with my wife,
With every word that was said,
It became quite clear
For my life I held dear 
I should keep eyes 
In the back of my head!"
