You just committed fraud. I'm pretty sure that it's a felony. My advice is that you delete this question as it is evidence that you definitely knew it was illegal.
Also this can go down as theft if it was someone else's number and if what you purchased was over 20 dollars then you can be sued in civil court, where your age really wouldn't help you.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
