This is a nice poem about growing up. Digging clay with one's fingernails is a part of one's childhood. Letting the clay cook in the scorching sun is another way of enjoying the summer. Spades are put in to dig the clay. The children also fall asleep under the sheets and beach chairs. The poetry shows the carefree nature of childhood and how we are so adept at having a mind that is free of worry. Teacups are empty so are the beach chairs. The games one dreams up are so much very real. The poetry is very much about being a child and enjoying it.
