I watch my son playing with his toy cars on the lounge-room carpet, making vrooming sounds and crashing noises like I did when I was his age.
I still have some of my own old cars which I have given him, which he adds with glee to his Lightning McQueen collection and that other Disney character whose name I always forget.
I watch and smile at his expression of intense concentration, lying prone on the floor as he pushes them to some imaginary destination; I feel that warm glow inside, and realize that I am the continuation of my father as he is the continuation of me; and that it is through our children that we will truly live forever.
