Young beggars become a "natural" element of the metropolitan life. The aim of the paper is to introduce to the phenomenon of the street children and analyze it on the base of the psychosociological concepts of the process of growing up, and in the context of macro social and economical changes in Poland which reflect on the family's everyday life and on the relationship between child and parents. We will focus on the questions of the 'begging' as the process (learning the role, playing the role etc.), as a style of life, as the economic strategy of the family, as a social problem.
