I sent my three-year-old son to the school bus today, and he was sitting next to his good female classmate. Last month we ran into each other at the playground in the mall, and he directly kissed her on the mouth. Both sets of parents were shocked on the spot. Today I watched him the entire time, and I could see him plotting to do it again—my scalp went numb. Fortunately he didn't manage to kiss her. He's three. He's only three years old.
