How Did This Happen?

I am an introverted person who enjoys being alone for long stretches of time-- I like to read and play the guitar and write sentences and listen to music-- and I have trouble thinking about more than one thing at a time, but somehow I've gotten myself into the absurd position where I have to: 1) be the boss of over a hundred kids during the school day . . . I constantly compel them do things that they would never do on their own: read Shakespeare, write essays, perform skits, and draw horses (I especially love compelling kids to draw horses, because if you can't draw-- and the bulk of the population in America can't draw-- then drawing a horse is especially comical) and then 2) after school I have to lord over my own children, and compel them to do homework and clean-up their shit and eat their dinner and brush their teeth and stop fighting, and now 3) we've added a dog to the equation, and I've never had a dog, but everything I've read explains that you have to establish yourself as the alpha and show the dog who's boss and my friend John gave me this advice: "Dog training is easy, you just need to establish that you are the master," and that makes sense, of course, but I often wonder: How did this happen? because I would be perfectly content being The Boss of No One and The Master of Nothing.
