Is AUTHOR wrong in the post ? POST : I'm a student from a middle-income family in a selective public high school which charged a freaking high tuition and fees. Because of that the students here are crazily rich. But my family managed to merely pay those fees for my education, and we're not talking about that.

The thing is, after multiple selection rounds, I luckily got into the National Mathematics Competition (USAMO equivalent) team in my school. As a requirement, I took extra advanced Math classes to improve my skills and prepare for the competition. This is where things get crazy: the school's officials invite some professors to lecture us about more sophisticated subjects on Math. 

At first, I thought these lectures would be free of charge, as they were settled on the school's behalf and there weren't a notice on fees or whatever. But until recently, the school's principal called my dad to inform the tuition, stating that the school required the family to partially pay and support the limited budget of the school, and he insisted on not telling me about this. He also called the rest of the team too, telling exactly what he wanted their families to do. My family, however, discussed with me on this subject, and decided that we wouldn't pay because of our financial circumstances. Thus, we did not respond to the call.

Yesterday, my principal wanted to have a word with me. He told me that he had called our family about the issue, which I already knew, and said that he wanted me to force my family to pay the tuition. One thing he said that really bothered me: "All of them paid their parts, except your family. Each of the families pay at least 1000$ for this. I understand you conditions, but your family have to pay, at least 500$, for it because you took part in it. If the team finds out that you didn't pay. They will see this matter as unjust". 

I was at a loss for words. I wasn't noticed for the tuition before I enrolled in these lectures. And now I'm facing discrimination because I didn't pay for this. My family and I are stuck in the limbo; we are undecided about paying it. Maybe we will not pay it, but I'm not sure what I will come at.

So... AITA for not paying the fees in this case?
