[There is a concept among the Russian bratvas called a "torpedo", which is what Niko is. A man hired to trail and eliminate a specific target. But Niko doesn't look everywhere for a threat, despite his paranoia, he looks for very specific threats. So when he sees shame cross an old man's face he misinterprets it as something completely innocent- after all, Smiley is a respectable looking older white British gentleman of a higher class than he is. And even here, a million lifetimes and a whole universe away from home he's aware of his class.]

You know, well, some of us have it hard everywhere because of those bad sides. Don't feel too bad about it. I wish more people would look in those directions, see how hard it is to work their way up and the things that you have to do, sometimes things you really don't like.

As long as you know you're pretty lucky.
