We never know what someone else is going through and what their day might be like. The senior citizen that lives near you may have no one to talk to during the day and your smile and friendly “Good morning!” greeting may be the only one they get. The cashier in the supermarket may have been dealing with difficult customers and the joke you tell them could be their first laugh of the day. The rushed driver in heavy traffic may have received some troubling news and you letting them get ahead of you could make a difference for them. You just never know. Your positive energy can be contagious and you can make someone happy just by smiling or saying “Hello”. So why not share a little kindness with everyone? Try it and see what happens!
