This is my life
Hi to you all!!! My name is Gregory, Greg for my friends, and especially for Sandy, my girlfriend. Can you see us together on this picture taken by my little brother Simon after school ?
I go to Springfield High School in a nice suburb of Los Angeles. I live there in a big house with my parents, my brother and my baby sister Sue. My father’s name is Mark, he is 45 years old, he is a vet, my mother is two years older than my father and she works as physiotherapist. I just love my parents because they are fantastic, really understanding and good fun. Simon can be naughty sometimes but he is Ok, he’s 13 years old and he is crazy about computers, he spends hours surfing the net, he plays games on line with all his friends, but he never practises sports which enrages Dad, because we live two minutes from the sea and he hardly goes there for a swim or a run! Sue is so cute, she’s an adorable baby of 13 months old now. She walks a little by now, yet she keeps bumping herself in all sorts of things in the house.
I for myself am now 15 years old, I love school, drama and sports. I go to drama lessons twice a week with Sandy. We also go surfing every other day. You know the beach is so close, so we also go running there once or twice a week. I play the drums in a band too. And what’s more, since I am an early bird, I walk our three dogs every morning and evening because my parents are too busy to do that and Simon ……. well apart from his computer! We also have two cats. So you see, my life is quite active but I couldn’t imagine any other, I hope you like yours as well as I love mine. Take care!

3. His parents are separated.______
4. He has a brother and a little sister.______
