　　B

　　In England, we look forward to our birthdays for 364 days a year!

　　We invite special people to celebrate it with us.

　　The Presents

　　Presents are opened as soon as the children are awake. They can't wait for the birthday cake later in the day!

　　The Cards

　　Friends and family send birthday cards. Sending birthday cards is a custom (风俗) that began in England about 100 years ago.

　　The Party

　　The birthday child will have a party to which friends and family are invited. Visitors to the party bring presents for the birthday child. The children play games such as Musical Chairs and Pass the Parcel.

　　The Cake

　　The birthday cake is decorated on a theme (主题). A candle for each year is lit and placed on top and the child blows out the candles making a wish. We don't put objects inside the cake as stated on many websites.

　　The Bumps (生日举放仪式)

　　It used to be traditional for the birthday child to have the bumps. Friends would hold the child by the legs and under the arms and lift the child up and down bumping them gently on the ground. The number of bumps given is the age of the child plus one for extra good luck. As this can be dangerous, clapping (拍手) is often done instead.

　　The Sweets

　　Some children do take sweets to school to share with their classmates on their birthdays.
