Sometimes, I met someone new and take photographs with valuable stories by in their physical appearance, emotions or on how they move.
Taking photographs from strangers is dangerous at some point.
But from the other side of taking photograph to strangers is actually great.
You can get them as your content and document it.
When I'm taking photographs, i sneak and making my hand, eyes and cameras sure ready so i can just take a shot and put it in my bag and after that, act innocence.
