‘The Quakers rejected the use of you as a polite form of address, and preferred thou, which to them signalled intimacy and equality. By refusing to use you because they took it as a deferential form of address, the Quakers provoked hostility from others who regarded their behavior as a sign of contempt. The repercussions of such deviant usage were severe for some Quakers such as Richard Davis, who reported that when he addressed the lady of the house in which he worked as thou, “she took a stick and gave me such a blow upon my bare head, that made it swell and sore for a considerable time. She was so disturbed by it, that she swore she would kill me.”
