(I worry about you a great deal, Mma. I worry that you will take all the cares of the world on your shoulders and that you will collapse under the weight. I worry that you will open your heart to so many people that eventually it will be full-crowded-and it will stop because there is no room for the blood to go round. I am worried that you will look after so many people that you will forget that there is one person who also needs looking after, and that person is you, Mma. I am worried about all these things.)
