Is there something in the culture where you live that might make him afraid he would be judged for using a bike or public transportation? I am often stunned by the things you post - you seem very worried about how people will react to your cycling, wearing cycling attire, etc.

Also, whether he has children has nothing to do with anything. His personal life is not your business.

Whether you should have said anything -- does he report to you? Or was your work/life negatively impacted by his absence to an extent that would justify your commenting?
