That's what spending time with the young can do -- it's the big payoff for all the pain. The young can exasperate, of course, and frighten, and condescend, and insult, and cut you with their still unrounded edges. But they can also drag you, as you protest and scold and try to pull away, right up to the window of the future, and even push you through.
Maybe children just want whatever it is they don't get. And then they grow up and give their children what they wanted, be it silence or information, affection or independence--so that child, in turn, craves something else. With every generation the pendulum swings from opposite to opposite, stillness and peace so elusive.
