Student: "The distance to the far end of the circle is three."
Me, skeptically: "Where is the 'far end' of the circle?"
Student, gesturing: "On the far left side."
Me, intentionally choosing a point on the left that is close to, but clearly not, the farthest left: "Oh, you mean here?"
Student pauses: "I understand what you are trying to do. But I don't know how to be clearer."
Me, surprised: "What am I trying to do?"
Student: "You are trying to force me to be more precise in my statements."

Pretty impressed at how this student has me entirely figured out after four days.

@phonner That is cool! And so the math teacher becomes an English teacher. "What word do you know that would be more precise?"

Ah ... too young to know about "The Golden Shot" ... up a bit ... left a bit ... right a bit ...
