It's a sunny day today. In the morning, we all agreed that my dad could do whatever he liked on his birthday. We thought he might go out for a drinking spree or maybe just play his games. But to my surprise, he spread out my math books and decided to teach me math. That caught me off guard. Who in the world would choose to teach on their birthday? We went through ratio problems, practiced fractions, and so on. Even though it's still my New Year break, I couldn't refuse. This is insane!
