Upton Sinclair,
King Coal — Book II Chapter 8
(1917)
“ When Mary Burke entered, Hal divined from her aspect and manner that she had sunk back into her old mood of pessimism. He felt a momentary resentment. He was so thrilled with this adventure; he wanted everybody else to be thrilled--especially Mary! Like every one who has not suffered much, he was repelled by a condition of perpetual suffering in another. Of course Mary had good reasons for her black moods--but she herself considered it necessary to apologise for what she called her "complainin'"! She knew that he wanted her to help encourage the others ”
