My little brother said 'I'm the smartest kid in the class' when he failed spelling. He was 8. He looked like he was 80.

My cousin said 'I know everything' when she didn't know what a triangle was. She was 10. She looked like she was 100.

My friend said 'I'm the brain of the group' when he couldn't remember his own name. He was 11. He looked like he was 110.
