When Buster cheerfully insists that he will miss the Father's Day picnic because he has other plans, Arthur is convinced that he's really sad about his parents' divorce and embarrassed to show up alone.

When she gets a watch instead, Prunella can't bear to face the others, particularly since Muffy will be waring them to the big skating party.
