Summer is a wonderful time of the year. I spend every summer in my own interesting way. This year my vacation was great. In June, my mom and dad and I were at sea. There we visited a dolphinarium, a zoo and a water park. I had many good experiences.
In July, I spent time with my comrades in the yard. Once it rained heavily, and a lot of branches fell. Then my friends and I built a house of twigs, in which we had fun. We all went to a picnic, played football, volleyball and organized competitions.
In August, I went to the village to stay with my grandparents for two weeks. There I learned to milk a cow, take care of chickens and ducklings. And the most memorable was the fishing. Grandpa made a fishing rod for me and I caught my first fish. The summer was wonderful. The holidays left behind many pleasant memories.
