Read some information about gift-giving in the UK. Read about each occasion and talk to a partner if you have a similar or different custom in Viet Nam. ● People in the UK often receive presents on Christmas Day and on their birthday. ● On Christmas Eve (24th December), parents often put presents for their children in Christmas stockings and leave them in the children’s bedrooms when they are asleep. Children believe that the presents are from Santa Claus who comes in through the chimney. ● On their 18th birthday, when people become adults legally, they may also receive a silver key as a present to symbolise their entry into the adult world. ● Chocolate eggs are often given to children as presents at Easter, which is celebrated on a Sunday between 22ndMarch and 25th April. ● The most popular presents for mothers on Mother’s Day are chocolates and flowers. Mother’s Day is on a Sunday, and usually falls in the second half of March or the beginning of April. Example 1: Student A: I don’t get presents on Christmas Day, but I get lucky money on New Year’s Day. Student B: Oh, really? I get presents on both Christmas Day and New Year’s Day. Student A: Lucky you! Example 2: Student A: Do you give presents to your mother on Mother’s Day? Student B: No, I don’t. But I give her flowers on Women’s Day. Student A: I do, too.
