Children, or the master of evil...

Lynn and I just watched Harry Potter and the Deathly Hallows Part 2. And, at the very end, as we see Harry, Hermione and Ron on Platform 9 3/4 at Kings Cross, as their children depart on the Hogwarts Express, Lynn says: "Gosh, they all look so tired." And I said, "That's because they have children. Fighting the master of evil is one thing, but at least you get to sleep at night."
