Whenever I've done a good deed, there hasn't been someone with a camera around to record the moment. But that's fine. That's not why you do something like that. You just do it because it's the right thing to do, and because you'd want someone to help you out in a time of need.
These are not the sort of people to grab the headlines, but maybe they should be. Maybe more attention should be given. We all need reminders that there are good people in the world just looking out for each other.
