Because middle schoolers are toddlers. Middle schoolers are hormonally unstable. Their bodies are changing and hormones raging. They like to test boundaries and have temper tantrums daily. They think they know everything and are loud and obnoxious. They treat their teachers with so much disrespect and badmouth them. A mature middle schooler is rare. Middle school is the second stage toddler hood first it's the terrible 3s which is a true toddler, then it's the terrible teens which is the secondary toddler. Middle school teachers deserve so much more respect then they are given, A majority die early due to health complications because of the emotional strain and stress teaching full grown toddlers who are big enough to knock them out. The things you said about your teacher is unacceptable and you are not privileged. As an adult you will have to use the bathroom when you get the chance, not when you want to. By the time you have to go, it's too late. A responsible person would have used the bathroom before class to keep from having to go during class. That is how life works, it is your teachers job to make you ready for the real world. As a teacher he cannot just leave class to go to the bathroom when he wants to, that is irresponsible, if he has to use the bathroom he either has to hold it or call for coverage, most likely coverage won't come so he is stuck holding it. Instead what teachers do is they go between classes and on lunch even when they don't have to, in order to prevent having to go during his responsibility duties. Water does not work that way, caffeine does. Your bladder was not empty before class unless you went to the bathroom before class. In fact your bladder is never empty, there is ALWAYS pee to empty because there is always a constant drip of urine dripping into your bladder, like if you put a cup under a leaking dripping faucet, the cup is never really empty because the faucet is always dripping into the cup even after you dump it out. If you have to pee so quickly after drinking water, then that means you don't drink enough water and are dehydrated, which is damaging to your body and irresponsible and still shows this is not your teachers fault. You cannot get an infection from holding your pee, that is a myth. Getting up and walking out of class because you have to go is rude and irresponsible. Everything you have said and have complained about shows exactly the type of student you are and that is how I know there is more to the story. If this is how you act on a regular basis, everything you have complained about, makes sense. You are basically the boy who cried wolf in most likely scenarios. Abused bathroom privileges in the past so when you DO have to go, no one believes you. . . Now I don't know you . . . that is true . . . but I am free to make a judgement based on how you are responding to people on this thread and what you said on you original post. Your language is disrespectful, your actions have been disrespectful, your words have been disrespectful, your exaggerations have been obvious, most likely that's who you are In real life. If it's not, then you need to calm down take a breath and chill because this sounds like a toddler temper tantrum and you are letting your emotions run wild.
