Sound advice right there. I really should follow it more closely though, since I don't really lock my laptop or anything, and someone could probably nose into my recent document history if they were really -that- nosy. Fortunately that's not the case for my immediate family, who pretty much all know of my orientation as of the December of 2011 anyway.
In fact, I'm reminded of an unfortunate incident where my habit of falling asleep with the laptop next to me on my bed combined itself with browsing [the sort of porn I usually browse]. I got woken up by Dad the morning after, who nudged me awake and left just before I realised what he saw, and on doing that hurried downstairs to apologise for what he saw out of concern: his answer ended up being that he's "seen far worse". I think I really lucked out on having such cool parents. (Oh yeah, and lesson being don't browse porn while sleepy.)
