Now, I admit that is a devastating story. It totally and completely sucks to have your world rocked like that. Did the daughter also find out that her dad wasn’t her dad? As I said, this is the kind of thing that tears families apart. And I don’t fault the boss for reacting the way he did. What’s weird is how the guy telling this story, who is also a father, reacted.
One day at work, his boss mentioned that, if he could go back in time, he would have tested his kids “on the sly” and then maybe this all would have been avoided. An irrational thing to think (he seemed to have no reason at the time to mistrust his wife!), but then again, this is a grieving man, and we all say things that make no sense in times of great stress.
