To explain how much of a dork I was, and still am, in high school... me and my friends in AP Chem used to write notes to each other on our TI-82's and TI-83's. We'd just pass the calculator back and forth during class. Sometimes it pissed off our chem teacher, but it didn't stop us. Even though that was more years ago than I care to think, I still pass notes or talk in class. Sometimes it is just innappropriate to talk in class so I just scrawl down my question on my notepad and show it to my friend. There is nothing immature about passing notes. Just another way to talk.
