I replied, "I got into MIT, Chicago, and Berkeley. Princeton makes its decisions next week. If I get into Princeton, I'll go there."
Q's face turned beet red. "You mean ... you're going to grad school?! ... In mathematics?!"
"Yes."
Not only had I done well in the courses I took from Q, but I had done well in general (I had already been named one of the few students to get junior year Phi Beta Kappa, and would soon graduate summa cum laude in mathematics). Had I been male, no one would have been surprised that I planned to go to grad school. In mathematics.
Q had clearly been planning to tell me something, but now thought better of it.
I asked, "What were you going to say?"
"Oh, nothing. It doesn't matter." He looked very embarrassed.
Curious, I insisted. "Please. You were going to say something. What was it?"
Hesitatingly, he told me that a math teacher at his son's high school had recently left. Q had thought that I might not have plans for next year, and would be interested in the position.
I deduced from Q's embarrassment that he would not have had this conversation with a comparable male student. But it's nice to know that he realized he should be embarrassed!
