Ben was confused about the toy he hadn't sent out. Hearing his subordinate's words, he frowned and said, "I bought it on the way to kindergarten. What's wrong? Is there anything wrong with grandpa buying something for my grandson?"
"No, leader, we don't mean that..." Lin said, "The main reason is that they don't know that you are their grandfather. There must be rules in the school that teachers or staff can't buy things for children at will."
"They have already called me grandfather. Didn't you hear it in the monitor? It means that they are very close to me!" Ben held his hands. "This is blood. This is family affection. This is grandfather and grandson. What do you know?"
No, I'm calling you Grandpa....
The three people behind him were sweating! That was just a form of address to a strange old man. He probably remembered that you were repairing trees, so he called you Grandpa.
