You know, I have to say here that what goes around generally comes around. Your mom's friend who was scammed obviously is a kind, trusting woman. We know she is trusting because she was scammed, and we know she is kind because multiple people in her life heard of her distress and tried to help her. If she were a total b**ch, would she have had several people trying to hand her money? So this is the case of someone who has been good to those around her, experiencing the same in return. It happens.
I know how you are feeling, though. Several years ago, my husband was laid off unexpectedly, J. after we had put our life savings down on our dream home. With our income more than cut in half, we were put in a position of using credit for everyday life while trying to keep up on our mortgage, thinking the situation was only temporary (that he would find a new job quickly). Well, that was in 2006, and we all know what happened with the economy and housing market. Long story short, we ended up $75K in debt, our home foreclosed upon, and the $200K we put down on the house, gone. I still want to cry J. thinking of it. We have since gotten our feet under us, but I have never forgotten that horrible feeling of losing everything of financial worth. Having been through that, hearing stories like the one you told give M. some faith in humanity. I love that there are people who hear that a friend had something bad happen to them, and because they can, they make it right. We don't hear enough stories like that. I don't have any scientific proof that this is so, but I do believe that the more you give, the more you will have. Maybe the rich couple who tried to help feel the same way. Life has been good to them, so they're being good to others. We should learn from that.
