Nancy's slap packed quite a punch, a crisp smack clearly audible.
Gro was stunned on the spot, staring at Nancy as he stammered, "You... what do you mean?"
Nancy asked with utter seriousness, "Who am I?"
"Of course you're Nancy," Gro shouted loudly, almost losing his patience. If he weren't overpowered, he would have truly been upset.
Nancy continued calmly, "If you couldn't see my face, would you still think it's me?"
"How could I not!" Gro exclaimed. "Even if I can't see your face, I can recognize your legs, your hands, especially the way you hit me, it hasn't changed at all!" Gro got more and more aggrieved as he spoke, his feelings turning to sorrow and indignation as he wildly speculated that perhaps Nancy was preparing to torment him like this in the future without admitting to it.
This... this was bullying at its worst!
