Wow... that's a wonderful story... good karma pays and it payed back to you... I wonder if we do something bad, we have to pay as well...
I too believe you do something good to another, it will help you somehow...maybe you earn their goodwill, and surely you inspire others to be good and make others believe that there are good people in the world too, because most times the world looks bad.
I love it, when I find examples that tell me there is good in the world too... although I mostly think its bad mostly...but anyway!!!
Parents know somethings through experience, and offer wisdom, but many times they misguide, because they have rigid attitudes. Actually, even they have to grow up as person along with us, learning and correcting ...learning from mistakes but I think most parents are too stubborn, and adament with ego to stay humble and learn and listen.
My parents are, and a lot of their advices and thoughts are wrong, I see it clearly now. But anyway...
That's absolutely correct, there's still load of good in this world, though not much but we can still find them.
Most times our past act is what help us unlock it just like my own case, I hope everyone finds help at the nick of time.
