In juvenile period man retires into his shell very often and reflects at substance of different objects. Forming of perception process has been continuing since his born. A teenager realizes his demerits. In this period a loneliness becomes his friend, despite the fact that it increases a number of personal and social contacts. When a teenager is alone, he reflects on his life, looks into life’s peripetias. In my picture he hasn’t got a face. For a while a teenager has no clear features. He sits above the precipice. It is the precipice of uncertainty. There are black and white lines over him. They are negative and positive thoughts. The color of the ground is green. It means that life is still lasting, and loneliness is only a short period in the teenager’s life.
