Dinner,for English people,is the richest meal of the day and is a very formal meal.Many people even wear special clothes for dinner,so if you are asked out to dinner you must find out whether you are expected to wear a dinner suit,for you would feel very upset if,when you get there,you were the only person in ordinary clothes.Dinner is generally served at about half past seven.All the members of the family sit down together and eat on their best behavior.The head of the family sits at one end of the table,his wife sits at the other end.If there is a guest,he generally sits in the place of honor,which is at the fight of the lady of the house.If there are several guests,the most important is asked to sit there.When the meal conversation is carried on,you should try to get in conversation with the person on your right or left,but you should not try to talk to someone who is a long way from you.
