Love you Forever

The mother sings to her sleeping baby: "I'll love you forever / I'll love you for always / As long as I'm living / My baby you'll be." She still sings the same song when her baby has turned into a fractious 2-year-old, a slovenly 9-year-old, and then a raucous teen. So far so ordinary--but this is one persistent lady. When her son grows up and leaves home, she takes to driving across town with a ladder on the car roof, climbing through her grown son's window, and rocking the sleeping man in the same way. Then, inevitably, the day comes when she's too old and sick to hold him, and the roles are at last reversed.
