bathroom and detention

i think it is unfair how we get a limited amount of bathroom passes because we cant control the way our body works. Also if its an emergency the teacher get frustrated with us and not let us go after class. What is with this 20 20 rule?? That is ridiculous. What if you really have to go? what are you suppose to do pee your pants and embarrass ourselves for their amusement? I don't think so. With the titan pass your suppose to have unlimited bathroom breaks so why do some teachers still sign your demerit card? Why would we get detention for having to go potty? If we really have to go and we use our restroom passes what are we suppose to do? We cant even go without getting in trouble. They need to calm down on the bathroom issue. If you got to go, you got to go.
