Things we notice

It is interesting what we notice from our apartment and on the way home...So I was coming home with my wonderful roommate Jessica, I love her to pieces. And we notice a certain guy waiting in his car, and this awesome girl comes walking out of her apartment crying... and we notice that this isn't the first time that this has happened. We both feel so sick about the situation, but we do not know the entire story. What do you think we should do? Should we just stay out of it or should we try to help in some way? We are at a loss in what to do, we are taught to love each other and help those in need but what do we do?
