I met an old friend yesterday while having lunch at a local cafe. It had been years since I had seen him and we used to be next door neighbors. After remembering old times and our parents (all deceased now) we were saying our goodbyes and he gave me some advice
"Just remember", he said, "a smile goes a long way".
I needed a few this morning, but, I hope to remember to give them personally as many times as I can.
