Have you ever gotten just really jittery? Not, like, from nervousness, though there is enough to be nervous about, what with Isaac the hacker and stuff. But no, I just feel really jittery - maybe I had too much soda today.
Outside my apartment, someone had spray painted some graffiti, but it was weird. It read "SNAPSHOT SIMPLICITIES" and below it, they had carefully written "So I crawled into bed and whistled out the light." I know I've heard that phrase somewhere before, but I don't remember where.
Didn't find a keylogger on my system, so Isaac must have hacked it some other way.
