We all owe everyone for everything that happens in our lives. But it's not owing like a debt to one person--it's really that we owe everyone for everything. Our whole lives can change in an instant--so each person that keeps that from happening, no matter how small a role they play, is also responsible for all of it. Just by giving friendship and love, you keep the people around you from giving up--and each expression of friendship or love may be the one that makes all the difference.
