I muse at all the little creatures I have held: tadpoles, hamsters, kittens, puppies and babies of the human kind. You hold them, feed them, love them, cherish them, rear them and scold them. Then the day comes when they seem a little bigger, and their bigness is at least as big as yours: You turn and look to see the little boy, once half a head lower but now exceeding the same as you did his. You scold him, and he holds his ground and challenges you. You fight him, but your power is spent and his is only scuffed in part..
So you surrender to him.
Next minute he tells you you are forgetting something; he has to help you out of your chair - just a little stiffness and he eases your socks on for you; cooks the dinner at the weekend, which soon extends to three days long.
And last not least he picks you up, you're feather light, and he's carrying you the way you once, in former days, would carry him aloft.
