This is exactly why I love old people. They aren't afraid to "get involved." They are from a generation that helped each other and took care of those who needed them. Nowadays, we're so afraid of lawsuits or feeling like it's not our problem, that many are willing to stand by and watch as our world is taken over by thugs and thieves. Be sure to watch the right hand side of your screen as she (in the red coat) runs from up the street and across the road to help. Notice all the people walking by and cars driving by and no one else comes to her assistance until she has several of the robbers down.
She's my hero.
