Dude I don't know trying to be nice. I think. Speaking to me after my first group ride. More on that later. (paraphrasing to the best of my memory.)
"Hey, you did well for your first time. In fact you were great.... Just remember that we've all been there. We've all been last or losers at something. Everyone is sometimes."
Update: I've had another opportunity to ride with this guy, and he really does seem very nice. I think he was trying to tell me to calm down and not worry about what the other riders think. That they all know what it feels like to be last. Which is a truism worth remembering in other contexts as well.
