When I walked into the house after school, I found my dad at home. What are you doing home already? I asked casually. Andrew, I was laid off today, he answered quietly.     I was sure he was joking. No, you weren't. Why are you really home?     Then I noticed his expression and realized he was telling the truth. My father has always been a hard worker and prided himself on his career. My father's unemployment created many changes in our lives. He was home all day, which meant my bed had to be made, my room cleaned up, and my homework done right after school. I would come home every day 下列说法中，正确的是（　　） A、到直线l的距离相等的两点关于直线l对称B、角的两边关于角的平分线对称C、圆是轴对称图形，有无数条对称轴D、有一个内角为60°的三角形是轴对称图形
