If your boyfriend asks you what color your underwear is, what does it mean?

Color is the most important word. People with no quality ask this question. Just kidding, ask the color of underwear. If you don't know each other, aren't you contemporary social hooligans? You'd better pay attention to such people ~ there is nothing worth teaching. Otherwise, you will regret that you realized that so many people were telling the truth that day. Why doesn't he ask you to change your underwear every few days?
