Payback?

When did I become my parents? I find myself, more and more, saying the same things to my kids, using the exact same tone of voice. The things my parents would harp on when I was little... sitting up straight, saying excuse me, keeping things neat. You know, those stupid parent things. Well, now I'm the stupid parent. When did that transformation take place? It's a scary thing. Maybe it's some sick joke being played on me by the Universe. A punishment for all the times I rolled my eyes at my parents. Pretty soon I'll be talking about how I used to walk to school, barefoot. In the snow. In June.
