The Tallest Tree

Were I a boy of nine, or ten, I would climb the tallest tree, and then, Leap carefree from the highest bough— Free of the fears that find me now. Do you recall when you were ten? And could you likewise be again, What exploits would you dare to try— And having not a reason why? Perhaps I am too learned now, Too wary of the highest bough. But were I a boy of nine, or ten, I would climb the tallest tree again!
