Eat the melon

Today, I learned piano back, mother gave me to eat melons. I said: "I can only eat half." Mother said: "that was cut in half!" I say: "good." Mother will give me cut half a melon, later, I ate ate, found some of which are yellow melon, I asked my mom is going on? Mother said: "that's because the ripe, it doesn't matter." I understand the meaning of the mother, the melon all finished, today, I've really had a good time!
