Pushing someone is undisciplined. Going to jail for doing so is punishment for assault.
Manners are the rules of polite society, so yes, they really do exist. Of course, everyone has the choice of opting out of polite society, but that choice comes with the consequence of being treated impolitely in return. No one made up manners "because their mind got bored," nor are manners a block to human progress. They are a means by which we avoid getting frustrated to the point of wanting to push someone.
For a thirteen year old, you actually write fairly well, much better than a lot of your peers. Stay in school, pay particular attention in English class, and you will one day be able to hold your own in an adult discussion. You are well on the way to being able to do so now.
Of course, you had the good fortune of being born into a society that makes education available to everyone. Had you been born in Somalia or Sierra Leone, you could be illiterate for real. You could also be sweating in the fields or in a child labor factory.
You and I are lucky to have been born in one of the fat lands of the world. I'm very thankful for that, and hope you are too.
Now quite p**** and moaning, and get that homework done! (just kidding)
