The more I read Mark Twain, the more I admire him, in many different senses!
In 1876, a couple visited him and his wife, and they had dinner together. The woman invited wrote on her diary, quoting him:
"Every man feels that his experience is unlike that of anybody else and therefore he should write it down -- he finds also that everybody else has thought and felt on some points precisely as he has done before, and therefore he should write it down".
Exactly! Nothing else to add!
