  Summer holidays are the longest and the funniest vacations in the year. We’re always looking forward to the summer vacations. And when they come, we put our school backpacks aside and completely forget about boring school life. It’s time to have fun and take a rest!This summer the weather was great! It was neither too hot nor cold. At the beginning of June (early in June), I decided immediately to enroll in the swimming pool, because I am fond of swimming. Dad insisted that in addition I should sign up for karate hobby group. He believes that every man should be able to stand up for himself. I also think so, therefore I gladly accepted the offer. My sister enjoys dancing, and we enrolled her in the dance-club.The whole June and half of July I was engaged in the hobby circle, walked and ran about the street with friends. From time to time I did the homework that teachers assigned for summer vacations. At the end of July we went to the sea with my parents. We sunbathed, made tours and talked with strangers there.In August, they bought me a summer camp voucher for 10 days. Camp is the most amusing place where I happened to stay. Every day we were doing something interesting and fascinating. We walked down the hills, went hiking, did rock climbing. From time to time we learned to draw, play the guitar and the synthesizer. But what I liked the most - gatherings around the campfire. We sang songs, told horror stories to one another and heated ourselves at the fire there.
