The other day as I was doing the dishes I looked out the window. A small gray squirrel sat on the ground and started to dig in the dirt. He started out slow and then picked up speed. His eyebrows wrinkled as he intently looked down at the ground and dug faster. He paused slightly and sighed, then went back to work digging. I could almost see steam come out his ears as he concentrated so hard on his digging.
Then he stopped.
His ear perked up and he sat there. He looked over to the side. Then he moved four feet to a location directly parallel to where he had been.
He found the nut he was looking for.
He took it up into the tree and sat down on the first branch he came to and ate it.
