¿Qué mala cara has visto? “What bad face have you seen?” The magazine Chilango describes the rule for when a guest gets up to leave. The host asks: “¿Qué? ¿Por qué te vas? ¿A dónde vas que mejor te traten? ¿Qué mala cara has visto?” (What? Why are you leaving? Where are you going where they treat you better? What bad face have you seen?)
The guest must answer: “Noooo, si estaba muy a gusto, lo que pasa es que tengo prisa” (Nooo, I was having a great time, it is just that I am in a hurry). According to the grandparents, Chilango writes, the host keeps acting offended until the guest stays a little longer.
