i'm with flibber on this one. tell us more about why you wish to manipulate your parents and we will consider your request.
"Sometimes i dont want to go to school"
Sorry, I don't condone willful ignorance, and your grammar shows that you're not skipping out of boredom with the curriculum.
I would have to know a lot more about your parents and your life than that they're "shitty" to give you a plan for manipulating them out of their money. Nothing you think you "need" right now actually matters anyway, not clothes or phones or whatever. It would be smarter for you to save up as much money as possible for later, to help with the low-income future you're heading for.
I made sure they wont.
MUAHAHA
no, actually i used fake medical documents i printed and had a girl sign them to look like a doctors signature and gave them to the school.
I was a really sickly guy :(
Later i started selling them for a while to lower graders. I had a collection of fake stamps, even had a special service: give me a picture or a document with the real stamp and i will replicate it on the fake medical documents. Since different doctors had different stamps.
Another girl supplied me with the fake documents... my own little school criminal empire. Did a few other things related to this too.
