Как у тебя получилось 7? не пойму! мама+папа+дед+баба+брат+ты=6! 
My family is quite big. There are six of us - my mom, my dad, my granparents, my younger brother and I. My parents Irina and Paul run family business - they have a little grocery store. Most of the time they are at work. My grandparents are pensioners. They usually stay at home. My brother doesn't go to school yet. We all live in a large apartment in a big city
