So, Bill and I had an argument. In class. Quietly. What about, you ask?

We are learning a computer program that is part of our Culture and Language Acquisition (CLA) practicum, and he was irritating me. Telling me where to move my curser and what to click. Telling me what to do and how to do it. I hate that. So I tell him, quietly of course, (we are in class after all) to stop telling me what to do. Then he tells me that I was doing the same thing to him earlier. Is he sure??
