i just got totally busted. NPR was playing some funky music between segments - i mean funky music, as in you can't help but do a head bob and chair wiggle music. anyhow, i had my headphones on and never heard the intruder. my face was pressed so close to the monitor that i didn't even see him until he was standing directly in front of my desk, imitating my head bob and giggling. i hate cubes.
