Graduations galore for this grandma. There won't be a busier grandmother around than Christina McCarthy this graduation season, when seven of her 24 grandchildren will graduate from high school. Checking the graduation dates, she said, laughing, "My poor calendar is so scratched out." In fact, 82-year-old McCarthy has so many graduations to go to, it would be physically impossible to attend all of them, since some will be held on the same day, at the same time.
