When the object of saying "Are you stupid" is your boyfriend, you must skillfully use the mode of coquetry and admiration between lovers, say "If I were not stupid, you would like me so much", then blink your eyes and believe that your boyfriend will pounce uncontrollably.
When the object of saying "Are you stupid" is your girlfriend, it means that your girlfriend is a little angry and unbearable about your stupidity. At this time, you should take the initiative to admit "OK, OK, it won't happen again" and then praise your girlfriend's newly manicured nails and beautiful clothes to change the subject.
When saying, "Are you stupid?" It's your best friend/buddy. Your best friend can refer to his girlfriend's model and praise her makeup, clothes and bags to change the subject. Women just can't help being praised. If you are a buddy, talk about the game you played last night, the game you watched, the new sneakers you bought, etc. to divert your attention.
When the object of saying "Are you stupid" is your boss, it means that you made a small mistake at work and the boss is already somewhat dissatisfied. At this time, you should take the initiative to admit your mistakes, and then seriously reflect on where your mistakes are and how to correct them next time. By the way, add some hot tea to the boss's cup and praise his bag and clothes to distract him.
In short, cleverly divert attention and make the other person forget the topic that you are stupid.
