My first close call with my interest in quicksand had to be in high school, primarily since I didn't have a computer and internet access at the time. During my lunch breaks, I would browse over to QSA's old sinking web art site and then to Stormwolf's (I think that was his name) story page; but, thanks to one of my nosy buddies, I almost had a heart attack one day when I decided to print up a couple of QSA's pictures.

One mainly being that it was semi adult material and I was afraid to be busted with it and that I didn't know what to say if they ever looked at them!
And around that time I started writing some stories based on QSA's works and while writing it in my dinky journal, one of my female friends was reading over my shoulder following everything as I had written for several minutes before noticing she was behind me. My heart froze, but she told me that the story was interesting and that I should finish it!

Thank goodness! Though, oddly enough she'd be one of the few people in real life that I could ever bounce ideas off of to further any of my written works.
When I later went to college and got a laptop, man oh man, Koal's sinking page made me freak out on several occasions much like reisen55 experienced. Though, the worst one was when my brother somehow accidentally installed the custom theme Koal used to have on his site, you know the one with Sylla and some of the audio from the video? That gave me a major panic attack as I didn't even know it was on the computer until my brother went somewhere he shouldn't and my family and I walked in on him. Needless to say, the both of us were going at it for a while as I honestly didn't know how it got there, even though I knew where it came from, and him looking at porn.

Thankfully, the issue was dropped, but I've still had many close calls since then, just not as major as this one.
