Lists abound about what you need to tell your children before they leave for college. But no "Top 3" or "Top 25" list can ever address the infinite worries, hopes and fears that accompany your children leaving for college. You want them to be safe but adventurous. You want them to be liked but liked by the right people. You want them to be friendly but not overly trusting. You want them to study but also have fun. You want them to miss you, but you don't ever want them to be lonely.
