In the United States, birthday parties are often accompanied by colorful decorations such as streamers and balloons. A birthday cake is often served with candles that are to be blown out after a "birthday wish" has been made. While the birthday cake is brought to the table, the song Happy Birthday to You is sung. Wealthy people or celebrities may hire an event management agency or a party service to organize a birthday party.
The cake, or something a pastry or dessert, is served to a person on his or her birthday , and is often decorated with small novelty candles, with the person's name and a message of congratulations inscribed with icing. The phrase "Happy Birthday " didn't appear on birthday cakes until the song Happy Birthday to you was popularized in the early 1900s
 Traditional holds that the person with the birthday may make a wish, which will come true if all the candles can be blown out in one breath
