Oh, please, ignore the guy and move on. Not difficult. And if your sensei and others are as infatuated with you as you indicate then what's the problem? As Michael said, pair up with the guy first to get it over with and focus on your training. Why do you care what this guy thinks? If the guy is an ass he is likely an ass to others as well. If it gets too much talk with your sensei.
Thanks, Keith. I appreciate the advice.
