Teacher Xu: "Bring me a sesame seed cake."
An Ning: "Sweet or salty."
Teacher Xu: "Salty."
An Ning: "Oh."
··························
An Ning: "Here, your sesame cake, 2 yuan."
Teacher Xu: "Um" suddenly blushed, "Xiao Ning, you said that we have known each other for such a long time, can it be cheaper? Hey, don't look so serious on your face, just let it be 1.5, I brought so much today."
An Ning: "Okay." Staring -
Pay, 1 yuan each, 5 cents for two
Keep staring——
Teacher Xu: "Uh--, um, give me 1.5."
An Ning: "Don't you still have 5 cents?"
Teacher Xu: "That's what I use to buy you."

An Ning: "I'm sorry, we only sell sesame cakes here, not people."
