There is another legend about his mother and his wife, involving a time when his wife was at home alone and was discovered by Mencius not to be sitting properly. Mencius thought his wife had violated a rite, and demanded a divorce. His mother claimed that it was written in The Book of Rites that before a person entered a room, he should announce his imminent presence loudly to let others prepare for his arrival; as he had not done that in this case, the person who had violated the rite was Mencius himself. Eventually Mencius admitted his fault.
