One of the biggest needs we have is for good mentors--whether it is in cycling, our job, life, school, etc. Give the guy a chance and maybe you might find a very rewarding experience. He may not want your help, but hey, he's into cycling--encourage the behavior--don't try to discourage him from the sport. I've been asked to mentor people I couldn't stand being around (at the time) and found them to be some of the most rewarding experiences.
