I was emailed earlier last week to sub for a teacher Thursday and Friday (one class only), and I told the AP I could do it. I didn't erase the message, so I would remember, and it got buried. I was thinking about the sub job the day before I was scheduled to do it, and for some reason, I thought it was for the next week. I went on to my regular class Thursday. I thought all was OK until the AP passed by me in the office later in the day... AP: "How did things go with Mr. Teacher's class this morning?" ME: "That was today??" AP: "Yeah. You mean you forgot?" ME: "Yes. For some reason, I thought it was for next week!" AP: "You mean they were totally unattended?" ME: "Yes." AP: "DON'T FORGET ABOUT TOMORROW!!" (with no yelling, but I could hear it in his voice that he was frustrated) ME: "Writing a note right now, before I forget!!" That was the first time in weeks I had been emailed beforehand about subbing for a teacher, and I usually write the notices on the board, but for some reason, this time, I didn't. I feel so embarrassed that I forgot to go to a class!! The next day when I went to the class, another AP was unlocking the door, and a student was telling her about the day before. They sat there the whole time, and didn't tell the office no one was there to supervise. When I asked why they didn't say anything, the AP looked at me and said something along the lines of they wouldn't say anything just so they could have a free day. This is only the second time that's happened since I started working here, and it's been seven years now. The first time was in my very first year. I just hope it doesn't happen again. I was kicking myself hard for that one! Others told me not to worry too much about it, that we all make mistakes. Thing is, I usually don't make mistakes like that!!
