The USA is the first country where Mother’s Day appeared.
On May 9th, 1906,an American Anne Jevis’s mother died. Ann was in deep sorrow. In order to memorize her mother, she put forward a proposal to fix a day as Mother’s Day. On May 7th ,1914,the Congress of the USA passed a law ,making the second Sunday of May “Mother’s Day”.
Today millions of Americans observe Mother’s Day in some ways. They buy more than 150,000,000Mother’s Day greeting cards. Companies produce more than 1,000 different kinds. Most of the cards show pictures of flowers, hearts or other things that people feel are linked to being a mother. They have messages that express a person’s love for his or her mother. Some are humorous. And some have no words. People can express their own feelings for their mother. Many people give flowers for Mother’s Day. It is one of the busiest days of the year for the flower industry. Many people have written songs about mothers and Mother’s Day.
Mother’s Day is a time for young children to do special things for their mother. Some would make a special gift or draw a special picture. One family activity on Mother’s Day is to have the children cook the early morning meal .Then they serve the food to their mother while she is still in bed. Or they might clean the house so she does not have to do it. Fathers might take care of the children that day so the mothers can rest, or take a walk, or read a book. Many mothers feel that this free time on their special day is a very good Mother’s Day gift.
Some families will get together for a meal at a local eating place. This means that mothers do not have to cook on their special day. Coming out to dinner has become a tradition on Mother’s Day. As a result, restaurants are extremely crowded that day. It has become one of the busiest days of the year for the restaurant industry in the United States.
Now Mother’s Day has been an international festival and more than 40 countries have accepted this festival.
