The old crow is getting slow.
The young crow is not.
Of what the young crow does not know
The old crow knows a lot.
At knowing things the old crow
Is still the young crow’s master.
What does the slow old crow not know?
-How to go faster.
The young crow flies above, below,
And rings around the slow old crow.
What does the fast young crow not know?
-Where to go.
