A lot. I do stupid things all the time. Just yesterday after testing I was reading a book, with my tongue stuck out between my teeth and lips. Some kid sitting next to me asked "Is that My Brother Sam is Dead?" (that was the book I was reading.) and I turned to him, with my tongue still sticking out, nodded, and went back to reading. It didn't occur to me until a few moments later what an idiot I must have looked like. Today in P.E. I also hit some kid with a football. Also today someone in science class asked me "Did we have any homework today?" I said "I don't know." Then, he asked "Do you ever know anything?" I wasn't really thinking, and I was working on a paper at the time, so I shook my head.
