On last holiday I was with my friend on the camp on Mazury. There we were leaving in wooden chalet. There was very small chalet but we didn't worry of it because we was spending almost all time off there. We were going on the lake every day and there we were sunbathing and we were playing volleyball sometimes. Weather was great but for few days it was raining. We were going on the forest sometimes. When I was becoming in Rzeszów I wasn't spending all the time in house so I was going on downtown, pool and much different places. I like sleep for late but my mum didn't allowed for that so I was getting up early. Afternoon I was hang out with my friends and we were talking and laughing. At the end of summer I arrived for my grandmother on the village were I have two cousins who I spent free time. There It was very much work so we were very busy for long time.
When holiday finished I went in school with pleasure.

During my last summer holiday I was with my friend on the camp on Mazury. We were living in a wooden cottage . There was very little place to move but we didn't bother that because almost all of our free time we were spending outside. Everyday we were going at the lake where we were sunbathing and sometimes playing volleyball. The weather was great but for a few last days it rained a bit. Few times we went to the forest. When I got back home(in Rzeszów) I didn't spend all the time at home-I often went out to the downtown, pool or many other places. I really enjoy sleeping unfotunately my mum didn't allow me to do it so I had to get up quite early. In the afternoon I was hanging out with my friends.We were chatting and laughing. In the end of the summer I arrived at my grandmother's house in the village were I have got two cousins with whom I spent my free time. There is always a lot things to do s we were quite busy there.
When holidays finished I got back to school with real pleasure.
