Father's Day has become important in North America. And businessmen found it was a good way to get people to buy a present for the fathers from their shops. By the way, very few countries have a Father's Day, though some have Children's Day, or a special day for boys and another for girls. More and more countries are having Mother's Day, so maybe Father's Day will become popular before too long. Now, what do people in North America do on Father's Day?
