In England, afternoon tea, taken between four and five, is the most informal(非正式的) meal of the day. If you are a friend of the family, you may drop in for tea without an invitation（邀请） or telling that you are coming. Very often it is not served at a table. The members of the family and visitors take tea in the sitting room. Each person has a cup and saucer(托盘)，a spoon and a small plate for bread-and-butter and cake. By the way, do not help yourself to cake first; bread-and-butter first, then cake if there is any. Another piece of advice: Do not put more than one piece of bread or cake on your plate at the same time.
