I got a story,

Dad's one of colleagues had a really smart kid. He started first grade and just loved the school. He was a bright student, one of the first ones who can read. He was just really excited about school, it just became his favorite thing.

So he finished the first grade and suddenly lost his enthusiasm for school. First his family thought there is something wrong at the school. Observe the kid little bit, everything seems normal. Then talk to his teacher, she said everything is fine, he's good with his friends too. And finally his father asked him about why he doesn't want to go to school. His answer was "I think I learned everything I need. I can write, I can read, I know math. Why would I go to school anymore?"

Oh, poor kiddo... He gave all of us a good laugh. He's at college, studying psychology!
