When I was born, my parents were living in a house in a small village about 20 kilometres from the capital. I was three years old when my brother was born and my parents decided that we needed a larger home. We first moved into a rented flat for fifteen months while the new block of flats we were going to move to was being completed. I don’t think my parents liked the rented flat because it was smaller than our old house.
We finally moved into the capital at the beginning of 1988. Our flat wasn’t really large, only 68 square metres, but there was enough room for two adults and two small boys. There were two bedrooms, a cosy living-room with a balcony, a small bathroom and a kitchen, where we used to have the family meals, as well.
I started school the following September, and my brother went to kindergarten. I still remember my first day at school. I even remember that there were 38 students in my class – but of course I’ve long forgotten most of their names by now.
We lived in the same flat all the time I was at school. I only moved house again when I started university in 2003. I decided to study forestry so I had to move to a town near the border. Rents were quite expensive, so I decided to move into a shared flat. Five of us rented a large flat in the city centre, and shared all the housework. I had the time of my life! I’m still living in the same town, but I’m sharing with just one person now. It’s more comfortable but I often miss the big parties we used to have at the other place.
