"What makes you think so?"
"Because you sit there and grin and grin all the time, and use big words that you know I can't understand. Where did you learn them?"
"At school."
"Oh, you've been to school, then, have you?"
"Yes."
"How long did you go to school?"
"Ten or twelve years, altogether."
"Ten or twelve years! What an awful stupid you must be!" She looked at him critically; then, with a modifying intonation, "Unless you learned a whole lot. I know I wouldn't have to go to school so long." She looked very decided. Then, after a pause, "You must have gone clear through your arithmetic. Zephyr taught me all about addition and division and fractions, clear to square root. I wanted to go through square root, but he said he didn't know anything about square root, and it wasn't any use, anyway. Did you go through square root?"
"Yes. Do you want me to teach you square root?"
"Oh, perhaps so, some time," Élise answered, indifferently. "What else did you study?"
