heres my explanation :) my usb is called grimey. i write a lot when it comes to journaling, but paper stuff is a bit not-so-private, so i got a usb. i write everything in notepad/docs then move it fully to grimey, which i wear around my neck.
if i somehow happen to die on the street (which i wont, im delusional enough to think i have plot armor) my family gets to take grimey and read my thoughts leading to my death. interesting, i think :)
