I just read this to Coop a bit ago... a little bit of Shel Silverstein is good for ya, no matter what the age. This one is from his newest book Everything On It.
YESEES AND NOEES
The Yesees said yes to anything
That anyone suggested.
The Noees said no to everything
Unless it was proven and tested.
So the Yesees all died of much too much
And the Noees all died of fright.
But somehow I think the Thinkforyourselfees
All came out all right.
