Trite but true-you don’t know what you have until it’s gone. People change. The world changes. And sooner or later you lose people you care about. If you don’t mind some advice from someone who doesn’t know much about families, I can tell you this: Don’t take yours for granted. It might feel like all of them will always be there. But they won’t.
