In England, afternoon tea is the most informal (非正式) meal of a day. It is taken between four and five. If you are a friend of the family, you may come for tea at any time. Very often it is not taken at a table. The members of the family and visitors take the tea in the sitting room. Each person has a cup and saucer (茶盘), a spoon (调羹) and a small plate for bread and butter (黄油) and cakes. By the way, do not help yourself to cakes first, bread and butter first, and then cake.
