I know exactly what you mean. This one time, a substitute came into my classroom and started telling me this long story about how he was a born reader, and how he always had books in his house growing up. He didn't like English, but he could write, and he wrote all the time. In fact, this one time he wrote a story and sent it to a science fiction mag. He actually used the word "mag", so I was kind of put off right away. I don't use the word mag, do you? Anyway, he started telling me what his story (the one he sent to the "mag") was about, but I wasn't listening. I was thinking of what to put on the board for the kids. I usually just put the Common Core standard we are doing that day and maybe a happy quote, but that day's lesson was new, so I decided to put an example question that went with the lesson. So, as this guy keeps talking, all of this stuff is going through my head, and I was like "sheesh, he can talk a lot!". I started to put the stuff on the board I wanted to and it hit me that I had to pee, too. So I started thinking about my quandary: should I pee first, or should I write the stuff on the board first? And all of these things were going through my head while he was still talking about this "mag" thing. At least I think he was still talking about it. Well, long story short, I forgot what I did first because this was almost a week ago.
