We all need a small burst of honest, sincere love. There are people who are looking to just make you smile. No interest in making money from you or taking advantage. Nothing in return. Just a smile. A wish that your day is satisfying. The sun doesn't ask for anything in return, neither should I. Knowing that you're happy is payment and knowing that you'll pass that along to someone else is secondary.
Be a hidden angel. A lucky coin on the sidewalk. An open parking space. A friendly smile on a hard day.
Be nice.
