I'd like to tell you one interesting story which i had last year. When i was sitting on the beach i saw a boy who was drawing the landscape. I have never seen it before. I went to him and decided to introduce, but he was shy and unsociable. In few day i saw him in local cafe and he also was drawing. In some minutes he came to me and gave my portrait. I was shocked, but i liked this drawing. Remembering it now i can't image that the shy boy was such a good painter!
