Doubles advice for USTA league play

I am partnered regularly with a guy who is a coach for a small high school. So I know he knows his way around the court. However, when we are partnered during a league match and I make a bad shot or have bad positioning, he often corrects me. Also, if I hit a ball out, he gets upset, and even threw his racquet on the court in frustration once. What would you do if you were me? Also, I should mention he is the captain of the team!
