In many countries, people celebrate one person's birthday with a big party. Members of the family and close friends are invited to the party. When they come to party, they usually bring some presents or flowers.

The mother usually makes a birthday cake, or she can buy it from a sweet shop. There are candles on the top of the cake. The number of candles is also the age of that person. For example, if he's ten years old, there are ten candles. There are usually a lot of candies, fruit, and drinks, too.

After the light is out, people sing the song “Happy birthday to you!” then play some games or sing or dance together.
