"I'm not a younger brother, don't hold hands."
The chubby little boy held his hands in front of his chest and hid them behind his back over and over again, exchanging back and forth for fear of being caught. His face turned red and his forehead was sweaty, but he refused to hold the little girl's hand.
"You are my younger brother. Your mother said you are 3 hours younger than me, so you are my younger brother."
