I have the most beautiful yard in the city especially in the summer. Around bed trees with flowers a green grass everything is very beautiful. Also in the yard there is a playground at which I play with friends. For kids there are small hills of a roundabout and a sandbox. Behind the yard in which I live the janitor therefore it always the pure looks after. But my yard is also beautiful also in the winter. All yard becomes covered by a white cover Trees are showered with silvery hoarfrost. Children ride a sledge play snowballs and build snowmen. I love the well-groomed and pure yard at all seasons of the year.
