I'm of a similar mind, being a greeter of strangers and especially kids. I always tell the kids they have a great bike. I've chatted with people who have traveled several hundred miles to ride the bike path here. I always give a "Good morning" to walkers in their neighborhoods so they know they need not fear the old man in tight shorts and shades. After all, I am in their neighborhood. I've been working at slowing down for 20 years or so and there is time to be friendly.
