Mister Rogers' Neighborhood (1968) : 13x2

Mister Rogers arrives with a piece of string which he takes to the front porch along with a pan full of soapy water. By tying the string into a loop, he is able to bring it out of the water and use it to make bubbles. As Mister Rogers is making bubbles, Mr. McFeely arrives and invites Mister Rogers to join him on a visit to Betty Aberlin's house. At Betty Aberlin's house, she, along with Mister Rogers and Mr. McFeely, watches as Mary Jo Barron sings songs with a small group of children. While everyone else enjoys a snack, Mister Rogers and Ms. Barron spend some time talking with each other about working with children.
