For a time, Jenny and Patrick enjoy a carefree period of 'going steady' but this is not enough for Patrick, who finds himself sexually frustrated. In the end, he gives Jenny an ultimatum: either she has sex with him or the relationship is over, and Jenny says she will. Patrick, after ensuring the absence of Graham, waits for her to come to his flat but she doesn't arrive. So Patrick has sex with a girl who, after Jenny's no-show, happens to knock on his door, a girl who is not only a schoolgirl but is also his headmaster's daughter.
