I am not sure I understand what your saying.
I see a girl running frequently on a main 2 lane road on my way home from work. I have talked to my wife about how naive she is, there are some very bad areas close to where she runs, she runs a predictable route and people drive like maniacs on the road. I would like to tell her what she is doing is not too smart but I don't even know her.
There are so many people that go through life thinking everyone is as nice as they are, the truth of the matter is, is that a good amount of people are little more than predators sizing you up.
