When your 4.5 yo says on our way back from school," mom, teacher was trying to give me challenging work. But she gave me easy ones like 10+3 and 10+10+10. So I told her this is easy. I can divide. And she said be quiet. Hahaha. Seriously, mom, why can't I go to 2nd grade. Why do I have to do pre-k, then k, then first grade?"
