'He kicks people at the slightest disagreement and curses at the drop of a hat. And this old brother of mine dares to boast that he's cultivated his character and developed a good temper? What a load of crap.'
Mr. Cheng was so thoroughly berated that he didn't dare utter another peep. With his old brother's explosive temper—a trait that would never change in a million years—letting him get angry enough to harm his health would be a crime.
"You're just hopelessly stubborn! And to think they used to say you were the sharpest one of our group. Sharp, my ass! You're so spineless, I can't even stand to watch!"
'Yes, yes, it's all my fault, I'm the younger brother here. I give up. Even at his age, that mouth is still incapable of saying a single kind word.' Mr. Cheng nodded hastily.
"Piss off!"
"Alright."
