Most people will,some people have motives whereas some people scared of you 'cause you're high profile. Not all of them will be fake ,because if the person you met not even know you're rich or famous ,can you just say he's faking? 'cause you no,because if he doesn't know he doesn't have the motives to fake it.
But i'll admit most of them will be different they may be scare of you or may be having some questionable motives.As for trust, that's no exact answer to this question,it depends on your discreetion. If you're rich ,just have to be careful.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
