If the family of Masha had not moved to our city 15 years ago, then we would not have met and did not make our best friends. If they had not become interested in biology at the School and were not engaged in the school circle, then they probably would not have become doctors. But if you want to become a good doctor, you need to study for a long time and work hard. If we had more free time, we would meet more often. However, we spend every winter in the mountains. If we didn’t know how to ski, then our vacation in the mountains was not so exciting. If next year we go to the mountains again, then try to learn how to snowboard.
