what did you do last summer ? Writ a paragraph ( about 80-100 words)

In our country, summer holiday is the longest holiday in a year. I often went to sea with my family and my relatives every summer holidays. But last summer, my parents allowed me go to sea with my friends. I had many memories with my friends and it made impression on me.
The trip had seven people; four boys and three girls. We learnt primary school together. So far we have been close friends. We spent three days on holiday. On holiday, we only slept four hours a day and the rest time we went swimming, went sightseeing
At the morning, we got up at half past four o’clock to see sunrise. It was very peaceful and calm in early morning. After that we went swimming. In the evening, we went along seaside. At that time the wave seemed gentler than it was in the afternoon. The later it was, the more people the beach had. Everybody looked happy. We took many photographs and had a lots of sea foods. All of us were indeed happy.
At the last day, there was a small problem with me. I had stomachache. Maybe I was not suitable with sea foods. Fortunately I bought medicine, so I took a medicine and I was ok.
After three days, we came back home. I think it was great time in my life.
