At first when I started subbing I would let kids go to the restroom when they wanted to, then I started becoming strict and wouldn't let anyone go unless they were dancing the jig. I had a class friday that was pestering me like crazy to use the restroom. I kept telling the students I wouldn't allow them to use the restroom, but they kept pulling my strings anyway. One girl kept pestering me persistantly. She told me "I have to use the restroom and on the way I have to stop at my locker." I told her if it was such an emergency she wouldn't need to stop at her locker. A boy behind her started laughing " dude! You totally don't understand why she needs to go to her locker before she uses the restroom?" He raised his eyebrow and gave a smile. I felt like such an idiot. Realizing then it was her period, I let her go. Shortly after three girls in the class started laughling and told me " Oh ya we need to use the restroom too, it's a girl thing." I made them sit in the room the rest of the period. They were gigling and laughing, persitantly teasing me the rest of the period. I became angry and wrote their names down for their teacher, but this only made them laugh even more. In our sub mannual it states sub's should not allow students to use the restrooms at all, unless under extreme circumstances. How do you distinquish between extreme or not? It is a lot easier to tell if a boy needs to use a restroom or not, he starts doing the jig. Girls are not so obvious in their body language.
