I saw a squirrel.
I took some nuts from my pocket.
Then I tapped on the sidewalk with a nut.
The squirrel heard the tapping.
When he saw me, I held out my hand.
After some coaxing, the squirrel came up and took the nut.
He came up several times.
I fed him the nuts until they were all gone.
Another time I saw a squirrel taking nuts from a man’s hand.
The squirrel carried the nuts to his hole in the tree.
