I used to think that when a child was born, a parent made a promise to stay with him. Or her. But if there's a promise, it can be broken. That first Matthew Trewhella broke his promises. I wonder if he ever forgot them, or did the torn edges of his promises hurt him to the end of his life? When someone goes away from you suddenly, without warning, that's what it's like. A rip, a torn edge inside you. I have a torn edge in me, and Dad has a torn edge in him. I'm not sure if those edges will still fit together by the time I find him.
