Yesterday I got up as usual at 6:30. I had my breakfast and 
went to the bus stop. I had to wait 30 minutes for the bus to come. It was windy and cold. And there were not many people there. It was very strange. When I came to my office, it was closed. I had to wait again. When I looked at my watches I understood that it was Saturday. When I came home I began to cough and sneeze. The weather was so terrible that it was easy to catch a cold. In the evening when I
took my temperature I was sure I was ill. In the morning the doctor came and told me what medicine to take.

I come back after a long absence in his native city of Perm. Perm is the largest city in the Kama region. Europe begins in Perm, the city is located near the Ural mountains. Perm is the largest administrative, industrial, scientific and cultural center, located at the intersection of transport and communications, and an important river port. In Perm there is a lot of vegetation, it is the most green city in Russia. Even in Perm, a lot of museums, galleries and theatres. Это 1 часть, дальше надо думать.
