This is the kind of day where no work gets done. (My students had today as a make up day for any work that they had not finished. So, surprisingly, some actually did work.) To pass the time, the administration puts on a movie for all of the classes.
There is a cable connection in each classroom. Since they only do this once a year, that connection is not connected to the TV. But I knew where it was, so I went about getting that set up.
I verified that the cable was connected to the wall. I verified that the cable I was using was the right one. And I tried to connect it to the TV. No luck.
After connecting, disconnecting, and reconnecting that cable, I finally got a picture. It was a little snowy, so I tried to tighten the connection. That's when I lost the picture entirely.
I finagled the thing some more, and I got it to work. Everything went fine for about 15 minutes. Then for no explicable reason, the picture went to snow and the sound went to white noise.
I managed to get it to work again. I went back to my seat. Then after another few minutes, the picture and sound went out just like they had the first time.
I was nowhere near the connections. The students had not gotten out of their seats, and they were nowhere near the TV. I lost the movie for no reason.
Not that it mattered. They weren't watching the movie.
Finally, after doing this three or four times, they called us to eat. After we got back, I didn't bother trying to get the movie back on.
