Father started a chain reaction that soon got out of hand when he asked his daughter to invite a less priviledged girl into their house. Actually, everyone had reason to like the rowdy but lovable young girl, but when she introduced the daughter to one of her acquaintances, and he turned out to be the towns "full grown" delinquent, father's sense of tolerance snapped. What father did not foresee was that the more he opposed this match, the more determined his daughter became to continue it. Meantime, the son's roommate from Colorado State has arrived on the scene, by name of Cody, and he makes quite a startling impression on everyone, including the youthful family genius. The culmination occurs when the daughter walks out of the house, threatening to marry the boy she has been forbidden to see. Only now does father realize how wrong his tactics have been, and he does an about-face by inviting the boy and his parents to dinner. Everything goes wrong in a series of humorous contretemps; but from the experience of both parents and children see each other's world with new and kindlier eyes. There is comedy, sense, and character to this plav by America's popular writing pair.
