"You know what, Mary?"
"You're pretty smart."
"You've got a high IQ, don't you?"
"Yeah. I could have joined Mensa when I was younger. I think it was either my PSAT or my ACT score that qualified me to join."
"I'd like to know my IQ. Maybe I should take a test to see if I would qualify."
"Um, honey... why would you want to do that?"
"What are you saying? You don't think I would qualify for Mensa?"
"I'm just saying I don't think you need a test to prove you're smart."
"Okay. I get it. What you are really saying is 'why take the test and know for sure that Mary has a higher IQ?', right? That's what this is about right? You think I'm better off not knowing than taking the test and proving I'm not as smart as you, eh?"
"Something like that."
"Thanks for the vote of confidence."
