I'm not a fool

Austin spent the weekend at Nonna and Papa's house. He did all sorts of things from planting in the garden to riding on the four wheeler. On Friday night, they went to the seafood place for dinner. Austin started talking to the couple sitting behind them. The lady asked how old he was to which he replied, "I'm five. I just turned 5." The lady asked him when his birthday was and he said April 1st. She told him that he's an April Fools baby. He answered, with his eyebrows wrinkled, "I'm not a fool." He doesn't quite get the whole April Fool's Day thing yet.
