...We moved to a new house a few weeks ago i changed school. At first i was a bit afraid but i made new friends sooner than i expected. The teachers are nice and everything seems to be working out well. And what about you? Have you made any friends in your new school? Do you enjoy studying there? Have you got any new subjects this year?
