1 If I saw this with my own eyes, I would take it up with my friends significant other first. To spare my friend some heartache. If I saw it again then I would take it up with my friend.
Good luck to you....
2 I'd have to be 100% sure what I saw was cheating before I took it up with anyone. I'm more of a "mind your own business" kind of person. But first, I'd ask the person I saw doing what I perceived to be cheating, "hey, what gives?" (or something like that).
But not only does the cheater hurt theirselves but their spouse, children, health, mental well being, emotional well being, the other person they are cheating with, and the list goes on from there. They do not understand fully what their action has for reactions from others. So If a friend was in that situation I would definately let them know what I have seen and allow them to make up their own mind upon what to do further about said situation.
And while they are making up their mind of course be there for them emotionally, mentally, physically, and metaphysically.
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.
