 Mr. McGuffy teaches Diane s class drama, starting with some warm-up exercises dancing to primitive music. So just what are Diane s weekend plans - is she going to see her boyfriend Mark, or perhaps stay at home with Gloria, her ultra-modern mother, in a world of her own? Miss Gordon s has a nude life model planned for the art class, but Mrs. McClusky might take some convincing. Diane has trouble maintaining the believability of Mark and fakes a photograph. She takes her mother s ring, and claims it is an engagement ring from Mark. Diane s mum finds letters apparently from Mark, and is convinced Diane s up to no good, and forbids her to see Mark any more. After school, Diane seems to have been stood-up by an imaginary Mark. When Diane goes home, she finds her mother has realized the truth. After a heart-to-heart, Diane hands back the borrowed ring. The following day, Diane is crying - her "boyfriend" has moved up North... Perhaps Diane could teach Mr. McGuffy a thing or two about drama?
