Sheldon Allan Silverstein (September 25, 1930 – May 10, 1999 / Chicago/ Illinois)

If we meet and I say, 'Hi,'
That's a salutation.
If you ask me how I feel,
That's a consideration.
If we stop and talk a while,
That's a conversation.
If we understand each other,
That's a communication.
If we argue, scream and fight,
That's an altercation.
If later we apoligize,
That's reconciliation.
If we help each other home,
That's a cooperation.
And all these actions added up
Make Civilization.
(And if I say this is a wonderful poem,
Is that exaggeration?)
