George & Mildred S05E04 A Driving Ambition

Mildred leaves the house, saying that she is attending her twice-weekly keep-fit class with Ann. Mildred is actually having driving lessons, which she has kept secret due to not wanting George to teach her himself. When George says to Ann that he is surprised that she is not at the class, she tells him that the classes have stopped. When he sees Mildred in a car with a man, he suspects that she is having an affair. Mildred, Fourmile and Ann are amused at George's suspicion. Mildred decides to let him continue believing that, so that he pays more attention to her than usual. The driving instructor comes to the house and George questions him, leading to George finding out the truth.
