Exactly what it says on the tin. This story is a brief, fun story about how a desire to help others doesn't take a holiday. In this, the world basically works how you'd wish it to--accidents happen, but strangers go out of their way to try to help, and said strangers are rewarded. Sort of seems to say that the little tribulations are as important as the big crises when determining the mettle of a man--but I could be reading a bit much into it.
What can I say? I enjoyed it. :)
