My husband and I saw this photograph on the Internets...
"How'd you know that was the quadratic formula?" I asked.
"You don't know that that's the quadratic formula?" my husband gasped in disbelief. It's like I just asked him how to drink water? He clearly thought it was a ridiculous question.
When he realized I asked a legitimate (non joking) question, my husband jumped up and went the white board in his office. He spent the next five minutes explaining the importance of the quadratic equation and the quadratic formula. I sat their in a trance; trying to take it all in. I had vague flashbacks to my sophomore year in Mrs. Johnson's algebra class. To me that was ages ago, but it was as if my husband had just walked out of math class. "It's a very important formula."
When my husband finished his math lesson he snapped the lid back onto the marker and said, "okay." As if he expected me to never again ask any more ridiculous questions about the quadratic formula.
"Okay." I snapped out of my trance. Still shocked that a math professor lives inside my husband.
