This year I had a very busy summer.
In June I stayed in Moscow. Every morning I went to the gym, where I had my trainings. After the trainings I had lunch with my friends in small cafes in downtown. Sometimes after lunch we went to the movies. Couple of times we played bowling together.
 In July  I went to the sports camp to Klaipeda, Lithuania. I had trainings there twice a day. But we still had some spare time. We went to the Sea museum in Klaipeda.That was really interesting.
In August I went to Sharm-el-Sheik, Egypt. I went there with my parents. We went there by plane. We stayed in hotel "Gufa". We spent a lot of time on the seaside and near the pool. We also had some interesting excursions. Best of all I liked the excursion on the boat. Some people were diving but i was snorkling. I saw different fishes there. Red Sea is absolutely beautiful.
 I really like the way I spent this summer!
