After my hard and busy school year my summer holidays began. i felt happy and began to plan a lot of wonderful things to do during my summer vacation. i was dreaming about far south countries i always wanted to visit but i had to go to the azove seaside with my relatives. the water was very warm there because you know azove sea isn’t deep. what i liked there - a lot of different kinds of entertainment there: "water mountains", water scooters and discos. there was nothing to do all day except lying in the sun and getting a wonderful tan. i was playing with my little sister on the sand and in the waves teaching her to swim. later i returned to kherson and spent some time in town going out with my friends, reading, listening to music, watching tv, playing computer games. after that i went to the sports camp where i spent seven days. it was very useful experience because i had to get up very early, to train a lot, and to rest very little. but it made me stronger and healthier. i was very happy to return home and i spent several days in my summer cottage, i helped my grandpa to dig the garden, to water plants, and to gather fruit and vegetables. i was fishing with my grandpa and we were cooking fish together. only insects were spoiling my good mood. i enjoyed floating by boat, swimming in the river and helping my grandparents. during my summer holidays i made many new friends, read a lot of interesting books, got to know a lot of useful things. now i feel ready to get back to school. i am happy to meet my friends and teachers.
