Summer is the best season for people. In that time most people have a rest. They can do anything what they want, because for that they have time. Summer is also the best season for pupils, because they have a holidays. They don't need to do such a boring work, they don't need to go to school everyday. Of course summer is also the best season for me. On my last summer holidays i had a lot of amazing days. There is birthdays of my friends. I was too happy doing handmade presents for them. Also somedays my family and I had a picnic with our friends. We played some games like volleyball and even I with my mate tried to catch a fish. Other days I spent with preparing to school and reading books. In conclusion, I can say that at all I enjoyed my holidays and I had great time. I hope you too.
