"Don't just shoot randomly!"
I'm sorry, I thought it was my job to escort you safely and eliminate problems before they become threatening. Next time I'll just let the Goblins have you, old man.
Unfortunately Amir/Kayle has a submissive personality, and will adhere to the social norms of the differences between nobles and commoners. The old man might have some training, but acts more like a manservant shooing away bothersome pests in a social circle than an experienced Knight.
