Aunt Da Die, help me! Explain the meaning of the article!

English people have porridge for breakfast. Their porridge is made of oats, not rice. Many English people put sugar in their porridge, but Scots always put salt. They never put sugar in it. English people never drink tea from a glass. In Britain, sugar and milk are usually put in drink tea. When you go to an English family for tea, the host or hostess always asks you, "How many cubes of sugar do you put in your tea?" Because most families leave home during the day. But when everyone is at home on Sunday, they turn lunch into dinner. In the evening, they eat more supper.
