Thanks for the nice comments.
Bike: It was mine, of course - not his Wal-Mart monstrosity - he was riding my custom built from frame up TriCross, Neuvation wheelset. Only a scratch on one lever, wheels are true. I was riding my tourer, another reason why he just bounced. Gag, a week earlier I let him ride my full carbon Roubaix, I can just imagine ...
His Family: Conservative, protective. I suspect they are glad to see him off the bike and back onto the couch - and have me be more of a pizza buddy.
Guilt: None, really. As suggested, I sense this is a early warning event - and perhaps he's smart to find something safer for him - like swimming.
Regret: Yes, I think this is my rant, something along the lines of letting sleeping dogs lie and not trying to be someone's life coach or cheerleader.
