I had one close call where my brother knocked on my door while I was *youknowwhat*. I managed to cover it all up before he came in, but it was CLOSE.
Thing is, I have a very rare fetish that would be incredibly awkward trying to explain. You know what I'm talking about, one of those really rare ones that no one knew existed until the internet was invented. I have my own computer, but I'm still careful about things. I use a separate browser for my online exploits, and all my downloaded stuff is in a hidden folder on a separate drive. To back it up even further, I named the hidden folder 'Registry.' I seem to be the only one in my family who realises that opening the registry doesn't mean the computer is gonna explode. That should be enough to scare anyone off if found.
The only problem is the internet browser on my Wii. Yes, I actually use that thing a lot. And only for this type of stuff. But I clearly have favorited websites that would give it away in an instant, but I can't for the life of me think of a reason anyone besides me would even think of using that.
