A man is teaching his son to play the piano. He tells the boy, the piano loves to be touched. On the counter near the two of them they have a bowl of fruit which the mother is painting for the first still life in her art class. Part way through the lesson the father eats a banana and the son has an orange. The keys get sticky from the sweetness on their hands. They have to stop fooling around and wipe them off with a paper towel slightly damp.
