I was explaining to my students why we needed to leave just a couple minutes early. "I have to go to the doctor. My husband thinks I'm mentally unstable," I joked. A student chimed in, "You'd be surprised how many people are mentally unstable. I am!" And just in case we didn't believe her, she went on and on about it. But maybe she's right. Maybe there are a lot of crazy people. And if that's the case its probably true. I'm probably crazy.
