(Peng Wan was ten years old. He took a sip of coffee and frowned in pain)
Wan: Mom, coffee is so bitter and unpleasant to drink. Why do you drink it every day?
Mom (laughing): Awan is too young to drink the delicious taste. You will know when you grow up... But don't exceed one cup a day. Otherwise you will get drunk.
Wan (seemingly understanding but not understanding): So drinking coffee can make you drunk just like drinking alcohol?
