He's giving you attitude. It could be caused by several things. You may be going to fast for him and he's aggravated. Go back to the simple moving off exercises for a day or two and see if he has a better attitude. Whatever you do, don't baby him and let him off the hook. If you slow down and he's still being that way, you move on and get the job done. CA's book explains this thought better than I do unfortunately. I would step back for a day or two and then move forward again.
