I was 15 years old and the first year of high school. Everything was new to me and I was such a newbie. At that time I had 2-3 year of programming behind me at an institution where they taught competitive programming. And I knew something about computers. Not much but more than most of my school mates. At that time I wanted to become "super cool hacker".

So we had this very very thought teacher for history which was also our form master. She really knows how to explained everything about history and in an interesting way. But while she was teaching we also had to write down notes from her powerpoints that were on a projector. And occasionally she would wait for us to copy everything and then move on with her lecture. But sometimes she didn't. This was frustrating as hell. The whole class would complain about this because you couldn't take notes down normal, you had to do it at double speed.

But she got one weak spot. She was not very good with computers. Our school computers were locked in some kinda closet so that students didn't have physical access to a computer and were also password protected. So I came up with the plan to plant wireless mouse in her computer so that I could control her mouse. At that time it seemed like SUPER HACKER MASTER PLAN.

So I got an opportunity one time when she left the classroom and let closet where the computer was open. I quickly sneaked the USB of the wireless mouse in the computer and then go back to the seat.

So THE FUN began.

Firstly I would only go back in powerpoint so that all my schoolmates could write down notes including me. And it was hilarious to watch when she didn't know what is happening. So then I would move her mouse when she tried to close some window. I would just move it slightly so she wouldn't notice that somebody else is controlling mouse. And by missing X button just by slight she would click other things and other things would pop up and now she had to close this thing so it became a nightmare for her. And she would become angry at the mouse and start complaining how the computer doesn't work and that mouse doesn't obey her.

One time when she didn't pay attention to her computer and projector I went to paint program and drew a heart and wrote we love you (In Slovenian Imamo vas radi -> See the picture below) and one of my school mates has the picture of it. We were all giggling and she didn't know what is was for. And I managed to close everything before she even noticed.

So it got to the point where she couldn't hand it more so she called our school IT guy so that he would check her computer (2 or 3 weeks passed before she called IT guy). And he didn't find anything. He was really crappy IT guy in general. So one week passed by and I still had messed with her mouse. So she got a replacement computer. Who would guessed all the problems went away (because I didn't have another mouse like that). I guess when our IT guy took the computer to his room and really thoroughly check it he found my USB.

So he told her what was the problem she was so pissed off really I didn't see her pissed off so much in all my 4 years in high school. She demanded the apology from whom did it. And at that moment my mind went through all possible scenarios... And the most likely one was that I was going to be expelled... And I didn't have the balls to say that I did it and I was too afraid... Thanks to God nobody from my school mates didn't tell that it was me.

While she waited that somebody would come forward there was one moment when our looks met and at that moment both of us knew that I was the one that did it.

Next day the whole class wrote the apology letter and she accepted it. But for the rest of 4 years whenever was there a problem with the computer I had to fixed it and she didn't trust anybody not even our IT guy at school. It was our unwritten contract that I would repair her computer to pay off my sin that I did. And she once even trusted me with her personal laptop.

So to end this story I have really high respect for her because she is a great teacher and great persons that guide me through my teen years. And we stayed in contact.
