In a Harvard study of several hundred preschoolers, researchers discovered an interesting phenomenon. As they taped the children’s playground conversation, they realized that all the sounds coming from little girls’ mouths were recognizable words. However, only 60 percent of the sounds coming from little boys were recognizable. The other 40 percent were yells and sound effects like “Vrrrooooom!” “Aaaaagh!” “Toot toot!” This difference persists into adulthood. Communication experts say that the average woman speaks over 25,000 words a day while the average man speaks only a little over 10,000. What does this mean in marital terms? . . . On average a wife will say she needs to spend 45 minutes to an hour each day in meaningful conversation with her husband. What does her husband sitting next to her say is enough time for meaningful conversation? Fifteen to twenty minutes—once or twice a week!
