defines precocious

Henry and I were hanging out, and making small talk at the Meijer Gardens turtle tank earlier this week.
"I think he poked his head outta his shell. He wants to see us, mama?"
A volunteer came out of one of the classrooms to talk to him.
"Hi, sweet little boy. Are you here to see the turtles?"
He rolled his eyes and gave her the teeniest of nods.
"How old are you?"
He laid down on his belly on the step in front of the tank.
"What's your name?"
He covered his eyes.
"Are you shy, sweetie?"
"No," he replied, "I. don't. want. to. talk. to. you."

I blushed.
