I have caught the bus into the city recently, a big ol bendy boy, and I was the only one to thank the driver. When did everyone stop thanking the driver?
Keep thanking the driver. Keep picking up the garbage in the park. Keep returning the trolley in the carpark. Keep doing the things that you know make the world better, even if nobody else does. You are a just a regular person, but you can make it better for the next person standing in the same place you are right now.
