Emily Mathias is a normal teenage girl. She lives with her parents and three sisters. She likes animals and she can to play the cello very well. A cello is like a really big violin. But her family is different from most families. Why? Because Emily and her sisters Anna, Mary Claire and Grace are identical quads. They were all born in 16 February 2000. The four girls have got the same long fair wavy hair and blue eyes, but their personalities are very different. Emily loves horse-riding. Grace is friendly, Mary Claire likes writing and Anna's interested in science.
'Our house is very busy,' says Emily. 'We have to help with jobs at home. Every Monday I do the washing during school. But I'm happy with my life. People often ask me, 'Who are you? Are you Anna?' Sometimes the teacher doesn't know. It's funny!'
