Mister Rogers says that Joe Negri has invited us over to meet a mandolin player. He uses a wooden block to pretend he is shaving in the bathroom mirror. In the Neighborhood of Make-Believe, King Friday plays his bass violin for Queen Sara and Lady Aberlin. When he and Queen Sara kiss affectionately, Lady Aberlin becomes confused and thoughtful. She asks X the Owl what love is. He consults his favorite book, “Benjamin Franklin Speaks,” which only says that love is good and wonderful. She asks Robert Troll the same question and he thinks of some examples, but none are completely satisfactory. Lady Elaine comments that you cannot love anybody else until you love yourself. At Lady Elaine’s suggestion, Lady Aberlin talks to Queen Sara who explains that, although Friday made her angry, she still loves him. Mister Rogers visits Negri’s Music Shop to hear Peter Ostroushko play his mandolin. Peter plays and sings a Ukranian lullaby and explains that his last name means “sharp ears.” He talks about how he learned music from his mother who liked to sing, and his father and other relatives who enjoyed playing the mandolin and other instruments. Joe and Peter play a duet version of “Tree, Tree, Tree” after Peter teaches Mister Rogers how to pronounce the Ukranian word for tree. Peter shows pictures of his baby daughter, whom he loves and plays the mandolin for. Mister Rogers says that love seems to be something that fills us up from the inside and the more we give away, the more we have to give.
