Being in a situation where someone you definitely don't want to know what your computer is full of (i. e.
parents or gf/bf), is standing right behind you staring at the screen and passively compelling you to self-restraint, i. e. not opening /b/ or pr0n, keeping messenger
windows hidden just in case, and hiding embarassing desktop or icons (or embarassing icon names, such as "My Shit" instead of "My Computer") with randomly opened
windows.
