Each teacher gives the birthday child a small gift like a pencil, an eraser or a postcard. The birthday child is also allowed to wear special clothes instead of the school uniform.
Lucy---I am one year older than Linda. Denmark is my country. A flag is flown outside a window to show that someone who lives in that house is having a birthday. Presents are placed around the child’s bed while they are sleeping so they will see them at once when they wake up.
Tom---I am as old as Linda. I am from Brazil. The birthday child receives a pull on the earlobe(耳垂) for each year in my country. The birthday person also gives the first slice of cake to his/her most special friend or relative, usually mom or dad.
