I believe that we are all our brothers' keepers. In my mind, this is helping anyone who is in need to the best of my ability. This could be monetarily, emotionally, mentally, etc. This also means acting if you see a potentially dangerous situation such as a blind person acting confused. It takes but a moment to stop and ask if there is anything you can do. If we all took care of each other, the world would be a better and safer place.
