No sooner does one think that you cannot expect from a person what he is not capable of thinking or doing, than one becomes tolerant. The difficulty is that everyone demands of another person more in the way of thought and consideration, in the way of kindness and love. He wants more justice and fairness on the part of another; and his standard may be so high that another person cannot keep to it. It is the high expectation from every side of what one has to receive from others, it is that which makes one disappointed. And generally what happens is that a person does not only sit quiet after being disappointed, he resists, and so the struggle of life continues.
