This was because right up until the early 18th century, it was the custom in Britain to take two meals a day, the main meal being at two or three o'clock in the afternoon. Thus we can calculate that when the guests moved to the drawing room after dinner to drink tea, the hour would indeed have been "about four or five in the afternoon."
因為直到十八世紀早期，英倫的飲食習慣為一日兩餐，正餐在下午兩、三點，由此推算，餐後客人移師客廳飲茶，正好應該是「下午四五點」。
