The Vieira family moved to the United States in 1981. At that time, they decided to stop speaking Spanish at home and only communicate in English. This was because they were now living in an English-speaking country. Now the Vieira children are adults, and they sometimes travel to Spain to visit their family and friends. But they cannot communicate with them. Unfortunately this is common. When people move to new countries, they often leave their own customs and mother language behind. This is a mistake because there are many benefits to knowing more than one language. One advantage of speaking more than one language is that you can communicate directly with more people around the world.
