"They mustn't know my despair, I can't let them see the wounds which they have caused, I couldn't bear their sympathy and their kind-hearted jokes, it would only make me want to scream all the more. If I talk, everyone thinks I'm showing off; when I'm silent they think I'm ridiculous; rude if I answer, sly if I get a good idea, lazy if I'm tired, selfish if I eat a mouthful more than I should, stupid, cowardly, crafty, etc. etc."
"Since time is the one immaterial object which we cannot influence -- neither speed up nor slow down, add to nor diminish -- it is an imponderably valuable gift. Each of us has a few minutes a day or a few hours a week which we could donate to an old folks home or a children's hospital ward. The elderly whose pillows we plump or whose water pitchers we refill may or may not thank us for our gift, but the gift is upholding the foundation of the universe."
