From Arthur Golden (born 1956), American writer, Memoirs of a Geisha, (1997):
Couldn’t the wrong sort of living turn anyone mean? I remembered very well that one day back in Yoroido, a boy pushed me into a thorn bush near the pond. By the time I clawed my way out I was mad enough to bite through wood. If a few minutes of suffering could make me so angry, what would years of it do? Even stone can be worn down with enough rain.
