“Every contact you make with a human being (or even an animal) is an experiment and a dangerous and therefore important experiment. It is dangerous because it can never be repeated. However serious, however trivial it may be, though you will afterwards make many others, perhaps more unusual, more intimate or more complete - that chance will not come again.Human contacts are dangerous, too, because they matter so much, and no one knows how much they matter. Even the most trivial meeting makes a difference, slight but lasting, to one or both. Intimate contacts make heaven and hell, they can heal and tear, kill and raise from the dead.These contacts are the fields on which we succeed or fail. I believe that they matter far more than anything else in life. What we are is written on the people whom we have met and know, touched, loved, hated and passed by. It is the lives of others that testify for or against us, not our own.”
