I called back in the afternoon, and the teacher said, "No problem, I'll send them down." Some time later, they still hadn't arrived, and the secretary hadn't seen them either. I thought maybe the teacher had been in the middle of something with them and forgot to send them down. I took no offense; it happens all the time, and I figured I would get to them later.
Well, even though it has often been the case where the teacher never sends the students down, this one smelled fishy to me so when I saw the teacher after school, I told her it wasn't a big deal, but I'd need to call the kids down later because I still needed to screen them. She assured me she had sent them down and said they were gone for a "reasonable" amount of time, and then came back to class. Who knows where they went, but they definitely did not make it to my office. Oh, those poor second graders: the teacher stomped off fuming that they had done that and swore she would take care of them it wouldn't happen again. Still, I had to laugh, I am sure the kids enjoyed their break.
