My sister Lily is a great artist. On the walls in her bedroom 'there are some fantastic drawings. In my favourite drawing ..... a wonderful white horse running across a river. .... a house behind the horse and ... some trees next to the house. But ... а person on the horse's back. In fact, ... any people in Lily's drawings because she only likes drawing horses.​
