Aukxsona and KOS, thank you very much for sharing your experience here.
Nothing can learn you few things like being without home, cold and hungry. It simply changes your perspective about lot of things.

I lost many of my pre conceived beliefs about right and wrong during that experience. It left me very bitter.

Yea KOS, I know exactly what are you talking about, it really leaves some bitterness. But on the other hand it makes real survivor from you.
