Not Very Well Brought Up

Dear Mater, for all of our sakes,
Do please keep in mind that it makes
Such trouble for us
When you cause a fuss
Because a few plebs have the shakes.

We know there's no profit or perk
In letting an invalid shirk.
The ones who can pay
Will do as they may;
The others can get out and work.

I've trouble enough and to spare
With bearding the wogs in their lair.
Now dash it, old stick,
When it comes to the sick,
You silly old bag, we don't care!
