It sure is hard sometimes to keep focused on what is good. What is right. Of remembering what our values are. Of always acting with integrity. Of working hard to keep that focus.
I have a friend in the US. He tells a story about a grumpy postman. One who used to fling the mail through the door at them with a grunt (if they were lucky).
So one day, my friend decided that they, everyone that works at his business, would love this man, and would demonstrate that to him a little more each day. First they offered him water on hot days. Finally, eventually, he began to take some. Then they would offer him a seat for a rest.
Gradually he came inside and spent a moment, then two, then five minutes, then more. They engaged with his life, asking questions about his family. More and more he melted. It took about a year. Now he is a friend and ally. Just because they chose to love this unlovable man.
