To wave or not to wave?

I'm a waver. I like to nod to people coming the other way and I like to say good morning to people I pass. I'm not sure if that makes me old school, old or just plain friendly? 

I would like to thank the guys riding past us who asked if Emma and I were all ok as we changed a tube after a puncture on Saturday's shop ride. This type of fellowship within the bike community is slowly disappearing. The willingness of those riders to give some thought to others and offer their assistance didn't go unnoticed and will certainly be paid forward.
