"Young Master?"
Si Ning blinked and turned to see Ah Dai holding the letter. "You can go." He said softly, he doesn't have the energy to check what Ah Dai had written but there were no doubts he wrote it according to his instructions which means he doesn't need to check.
"Young Master, Ah Dai didn't serve you any mango because it wasn't in stock but will Young Master like me to get some on my way back?" Ah Dai asked as he folded the letter and put it in the pouch secured to his waist.
Si Ning doesn't need to think of his reply with one look at the prosthetic arm. "No just deliver the letter and come home, I don't need anything and you do not have to buy me anything." He told him, saying one word at a time because if he didn't have it clear, Ah Dai might come back with a basket of mangoes.
"Yes, Young Master."
