I've went ahead and skipped my second class of the day for 2 months and my school doesn't even care.
That's a little too much. Do you think your teacher wants you to skip class?
I swear at him and also ridicule him for being old. He brings up me skipping class once in a while though.
Attending all your classes is important for your academic success and your ability to graduate school. It's wrong to skip classes and antagonize your teacher by ridiculing and swearing at him. You should stop skipping classes and bullying your teacher or otherwise you will future will be jeopardized since you won't be able to graduate.
Fuck the world with its rules.
I believe it's best to stop your behavior and learn to be a little more polite to your teacher and school. How do you think he feels to be put down like that? Your education will really matter in the future, so it would be great to try and attend again.
