This little old lady is just saying one thing and meaning another.
Before she saw Lu Manshan, she kept nagging about why he hadn't come back yet.
Now that she's seen him, she pretends to not care at all.
"I did not," Grandma Lu said, hands on hips, flatly denying it, "Stop talking nonsense."
Lu Manshan knew his grandmother's personality well; he let go of his mother and hugged Grandma Lu instead, "It's my fault. I shouldn't have gone two years without visiting you once."
At his words, Grandma Lu's nose tingled with emotion, and she couldn't hold back anymore, thumping Lu Manshan with her hand, "You little rascal, do you even remember that I am your grandmother? Two years without coming back, and when you come back, you don't even bring me a great-grandson!"
A great-grandson?
Hearing that last sentence, Lu Manshan: "..."
Bai Lu continued, "Manshan, what about your girlfriend? Did she come back with you this year for the New Year's celebration?"
