Chuck Aber stops to visit and they talk about things to do while it is raining. Chuck gives Mister Rogers a poster of Sam Weber, a dancer. Chuck does bird whistles and makes other animal sounds and then dances. Mister Rogers does some Tai Chi and talks about all kinds of movement. He says it is important to keep trying in order to get good at something. He reads some poems from the book “Rainy, Rainy Saturday.” He feeds the fish and wonders whether they dance or think that it is always raining because they are always in the water.In the Neighborhood of Make-Believe, it is raining.
