four o'clock
After breakfast my father gave us lessons till eleven o'clock ; and then my brother played till midday , when we went to walk together , whatever the weather was , because at that hour they relieved guard and wished to see us to be sure of our presence . Our walk was continued till two o'clock , when we dined . After dinner my father and mother played at backgammon , or rather pretended to play , in order to have an opportunity of talking together for a short time . `` At four o'clock my mother went up stairs with us , because the king then usually took a nap . At six o'clock my brother went down , and my father gave us lessons till supper at nine . After supper my mother soon went to bed . We then went up stairs , and the king went to bed at eleven .
