Homeless people are without many of the possessions that give identity. Without permanent residence, they have no fixed regional identity; they are everywhere and anywhere. Most have also left their families and professions; they are therefore without those networks by which the majority of people define themselves. Homeless people leave the world of public identity to enter what amounts to another world. Authors who portray the homeless in their works set about to depict and to understand this world apart from houses, jobs, and material possessions.
