All poeple go somewere

But where?
I'm in subway. Around me all kind if people.
And most of the time, when i'm in subwat, I wonder about them.
Who they are? Where is they go? How are they in there life, daily? Is some of them a good person or bad? I put my salf all kind of questions, and I have no answer.
Some times I remain stock on somebody. I try to descifre, to take a look in side of him or her, to make a smallest idea .... But is just ipoteticle, nothing true.
Human are very odd. They prezent him salfe to the publuc in some way, but in reality they are very diferent.
