(1) Although separated by many years in age, Carolyn's father and her son are remarkably similar. (2) A gray-haired elderly gentleman, Carolyn's father always carefully selects his clothing before he steps into the public view. (3) His greatest treat is to browse through encyclopedias, dictionaries, and almanacs to absorb scraps of knowledge, minute facts, and out-of-the-way statistics. (4) At dinner, he enjoys surprising his family with the annual rainfall of Australia or the average length of the tiger shark. (5) Billy, Carolyn's seven-year-old, also carefully surveys his clothing each morning to see what would best suit his mood. (6) He too loves to read, but he confines himself to children's books on exotic lands. (7) Just like his grandfather, at mealtime he parades his store of odd facts before the family, relishing the surprised looks on their faces. (8) Maybe the old saying should be "Like grandfather, like grandson."
