What does Octavius respond when Antony tells him to attack from the left

He says he will attack on the right and Antony can have the left. What was so good about the right side, who knows? Probably they were arguing about it just to prove which one of them was really in charge and which one was the lackey. Not a good sign in a partnership. You might guess that by the next play they’d be at each others’ throats.
