Almost each year I spent my holidays in the country at my grandparents’. I adore that place for its landscape. There is a nice river and the woods where my friends and I can gather berries and mushrooms. We also enjoy swimming in the river and sunbathing when the weather is fine. Apart from this, I’m always ready to help my grannies around the house or in the garden watering plants and gathering fruit and vegetables. I like going fishing with my grandpa and cooking the fish over the fire. And one more thing which is worth saying is that I have a chance to breathe fresh country air and forget about the dust and the smokes of the city. Indeed I have a great time in the country with my lovely grandparents. I wish I could visit them more often.
