I really struggled to find appropriate outlets for my humour for a lot of years...

"When people you know say "hello" what they are really saying is "are you still friendly since the last time I've seen you?" so just say Hi with a hint of warmth if you can manage it, because people are never going to stop greeting you anyway, there is no way to recoup the cost so might as well let them know "yeah, we're still cool""

For a while, I had the charming habit of refusing to return greetings, because I felt they were bothersome, inefficient and unnecessary.

The rules themselves are each tailored to some particular misstep I have made. The principles that emerged really were kind of basic stuff good parents, teachers or Mr. Rogers teaches you. That being less selfish is wise, paying attention to people is rewarding, and that there is a very big difference between listening to someone and waiting to speak. The principles are only words, and the rules are too specific to my own experiences to really translate. What matters is the intuition I had been building up from the moment I decided for myself that this problem was worth the effort.

I hope it helps.
