i think summer is the best season of all because it is warm, the nature is beautiful and we have great opportunities for rest. summer is a time of holidays. we can go anywhere, spend our time near a river or a lake on fresh, green grass, swim in warm water, or climb mountains, play different games, ride a bicycle and so on. i'm spending the summer holidays with my grandma. there's plenty to do. most of the time i swam in the sea and sunbathed. sometimes i lit a fire with my friends on the shore and we baked potatoes in it. it was wonderful. we told each other jokes, and did whatever he wanted. and i often went alone in the woods.
