We all go bumbling through life, meeting and forgetting people without much thought to it. You meet someone, you become friends or you don’t, you stick with them a long time or you never see them again. Certainly many of those chance encounters never amount to much. But we’re connected in ways great and small to everyone we meet – and probably everyone we never see as well. And every once in a while, you get a chance to make a difference to someone. If you’re lucky, you get to know when this happens. I was lucky.
