RUSSIA

'I am an only child and l live with my parents and my grandma, or 'babushka' as we say here in Russia. My grandpa passed away last year so Babushka left her house in the country to come and live with us here in the city. When I was young I lived with my grandparents at their dacha and in many ways they were like parents to me. I don't see my parents as much as I would like, as they work long hours. Still, we've learnt to make the most of our time together, so there's never a dull moment in our house!'
Natasha, 15
