"Have you done yelling at the computer screen, grandfather?" Vito is telling him with an inexpression face.
"You dare to say something like that to me. Oh God, please take my life now. all my grandsons are useless, and I live alone try to preserve the family heirloom and reputation," Grandpa Sun is trying to act pity in front of his grandson. He is trying to flatter his grandson in reality but every time he fails to do it.
"Do you want me to send you the knife or poison?" Vito tells his grandfather in open about his plan for suicide.
"Do you really want to kill your own grandfather?" Grandfather Sun is getting work up with his grandson answer.
"You told me about your plan for taking your own life. I just try to facilitate it as my filial duty." Vito is talking as usual in short sentences. He knows his grandfather must have something in his mind until he needs to lower himself to seek his grandson audience.
