i am on holidays now. summer holidays is  the best time of the year! i can do everything: rest a lot, wake up late in the morning (or even  in the go to bed late at night. and the most pleasant thing  that i mustn*t  go to school! the first month of the holidays is june. i decided  to spend it at home. so every day i meet my friends and we go somewhere together. there are a lot of new good films and funny cartoons in the cinema. we have seen 5 new pictures already! we go for a walk several times a day/ it is great! when the weather is fine we go to our aquapark. we like it very much and usually spend the whole day there. sometimes i  read books from the list of recommended literature on summer holidays. but most of them are dull and not so interesting.
