Prison.

A deeply depressed soul leads a double life. He conceals his real identity through the day. He pretends to be who he is not, fearing rejection by society. Every night, he fulfills a small part of his yearning by spending time with his real self. That is the time he just resigns to his inner desire of living a different and far more fulfilling life. Though a new morning comes every day yet he cannot break the shackles of fear to start anew. In one way, his house is his Prison where he has isolated himself by his own will, and on the other, it is the microcosm of the freedom-less larger world where he has managed to find a little freedom of his own.
