You may not realize it, but you are in the perfect place at the perfect time. You know that person you just smiled at? That may be the smile that makes them realize life is not as bad as it seems to be right now. And that person for whom you just held open the door? You just gave that person hope that there are, indeed, some people in this world who are paying attention and willing to help out a stranger. Sometimes it is the little kindnesses that make life bearable for people. You were the one who was there, and you were the one who made a difference.
