Old people are often extremely sensitive about what kids do on computers, considering they know more then them and they somehow have the thought that they'll hack and take over the world or something.
Here's what happened to me:
I once showed my friend how to easily access computers through the school's network. However, in an entirely different class, a different guy was "cleaning up" the desktop. So he decided to move everything into the trash to keep it organized. A friend of mine emptied the trash. However, I was somehow brought into this when the principal caught hold of how I taught my friend to access the network. So she went super paranoid and threatened to permanently ban me from computers for the rest of the year because I might of "hacked" onto that computer and deleted the stuff. Which I didn't.
Funny having a tech teacher that can't use a computer properly thinks like her. She also gets mad whenever I point out what she's doing wrong.
Sucks, eh?
I got suspended at school once for "hacking."
I was playing loving Halo on the computer. Wtf.
Playing games on a school computer is pretty stupid anyway. I almost got suspended when my tech teacher saw me play a downloaded game.
