" Howard resented the ache in his heart. He resented that it was there every morning when he woke up... He resented equally the ache and resentment itself. He resented his resentment because it was a sign of his limitations of spirit and humility, no matter that he understood that such was each man's burden. He resented the ache because it was uninvited, seemed imposed, a sentence, and, despite the encouragement he gave himself each morning, it baffled him because it was there whether the day was good or bad, whether he witnessed major kindness or minor transgression, suffered sourceless grief or spontaneous joy. "
