In the past six months or so, Zhao Hongjuan and Lin Xudong had been thinking about their daughter's marriage, because they had agreed that she would get married after graduating from college.
Graduation, referring to college graduation.
Now, Zhao Yi and Lin Xiaoqing had both graduated from college, but marriage had not been brought up at all. Zhao Hongjuan would often say, "Xudong, do you think Qingqing and Xiao Yi might be having relationship problems?"
Whenever Lin Xudong heard such remarks, he would always say carelessly, "What problems can there be? Qingqing is still studying."
"One can get married while studying. She's a graduate student now; how old will she be after she finishes?"
"You do the math!"
Zhao Hongjuan's anger soared as if Lin Xudong had said something outrageous, before launching into a tirade, "You don't care about our girl, but I do!"
