Hi! I am Peter and I am 14 years old. I was born in London, the capital city of England,
on February 5th, 2001. I love going to school, because I have a lot of friends there. I also
love studying. My favorite subjects are Geography and Physical Education. I live with
my parents and my sister Sue. Sue is older than me. She is 16 years old. She is nice to
me, but sometimes we fight. I guess all siblings do. My mother's name is Emily and she
is an English teacher. Myfather's name is Edward and he is a lawyer. I have another
sister Kim. She is married to Ben and they have two children. They live in Bristol, but
we see them every weekend at my grandparents'. My niece and nephew are very cute
and I love them. They have a lot of toys. I love spending time with my family. That is
why I love the weekends somuch.
