Bad news seems to be way more attention getting than good news. I'm happy to see good interaction between people.
Just a few days ago I was riding the bike in town when approaching an intersection to a small street, a pickup was signalling a turn in front of me. He was towing a large Cigarette type speed boat from the town launch ramp a few hundred feet away. I stopped and waved him through which momentarily made his life easier. I got a friendly wave in return and maybe as he encounters cyclists on the road he will see them as considerate human beings. I grew up in a rural and agricultural town and consideration was part of living in such a place. This is called building community. I'm appalled at the behavior reported every day in the news. I suppose such reported antisocial behavior is due to a feeling of being passed over and disenfranchised by society.
