About a year ago, I was climbing Good Sir Martin. A hiker moved out of the way to let me by. I gave a smile and a friendly "hello" and kept going. She responded grumpily and said "you're welcome." I thought I was being friendly but neglected to say the words "thank you." She was likely having a bad day, or maybe I encountered her after a dozen other bikers had gone by her. But her reaction was a wake-up call. Saying "thank you" goes a long way.
Super good point.
