One day I had the urge to print out 50 pages of Nicolas Cage's face in the school computer room.
Why would you waste school supplies like that?
I wanted to pull a prank against the school.
Do you really think that that is a good reason to use all that paper. What if you were the one who had to pay for that paper? How would you feel about someone who wasted your supplies the way that you did?
I wouldn't mind about someone who wasted paper.
I get you wouldn't mind, but it wasn't your resources that were being wasted at the time. You need to realize the silly pranks are not worth it and will get you in trouble.
