What a great story! I have always believed in Karma and what goes round comes around. So I like to wish people well, do good deeds like Bryan & generally exude Love, Peace & Happiness. My thought from this is:
When we incur debt we are actually paying it back after the event, with interest, so we pay back more than we borrowed.
So when we pay it forward, beforehand, do we get interest on it and actually create more good that what we intended?
I certainly like to think so!!
