Everybody has a birthday. Many children in other countries celebrate their birthday like chidren in the United States. They have a birthday cake, gifts, and sometime a birthday party for frineds. Frineds and family gather around a table with a birthday cake no it. They sing "Happy Birthday to You."Two American sisters wrote this song in 1893, but people still sing this song today! The birthday cake usually has lighted candles on it, and then blows out all the candles. If the child blows out the candles in one breath, the wish will come true. Other countries have different customs.
