Camila is 5 years old. She loves going to the park with Bruno, her father. They play ball and spend hours in the playground. On a good day, Bruno lets Camila buy a treat from the small snack truck.
One day, after playing all afternoon in the park, Bruno and Camila stop at the truck for a treat. Bruno buys an apple for himself. Camila gets a granola bar and some bubble gum.
When they finish their snacks, they begin to walk home.
"I'm tired," says Camila. "Can you carry me?"
"You're pretty big to be carried! Let's try this," says Bruno as he lifts Camila and puts her on his shoulders.
After a few minutes, Camila starts pulling her father's hair.
"Ouch!" says Bruno. "Stop pulling my hair. It hurts!"
"But Dad," she says, "I'm only trying to get my gum out."
