I like spring very much. When I have my holidays in spring I enjoy myself. It is very great to have holidays in spring. To begin with I shall walk with my friends if the sun shines brightly in the sky. I enjoy the blue sky and even spring rain. The spring rain is warm and pleasant. I shall watch fresh leaves and blossoms on the trees. I feel stronger and kinder in spring. Secondly I can go to countryside and have a walk in a forest or by a river with my best friend in spring. We enjoy playing ballgames. Sometimes we can lie in the sun and watch the clouds. Sometimes we can swim in a river if the water is warm enough. And at last if you do not like nature you can play your computer and enjoy your free holiday time.
