Analysis of Please, Go Away!

Many, many years ago,
I was told and taught
That helping people is a considerate thought.
But there is something else to know.

Ungrateful people are of a sort
Rewarding generosity with a shattering blow,
And quite happily taking a friend for a foe.
But who would have thought?

It won’t worry them to get me caught
In trouble or fraught
And they are not slow
To show how ignorant they grow.

Now, I really wish to say to this lot
That my opinion of them is very low.
But words keep sticking in my throat.
And I just let things go.

May be one day
Shyness will wear away
And I’ll be able to say
To these people: “Please, go away!”
