NOTHING HERE
We looked everywhere. Whatever was here is gone now —
or maybe it never existed at all. Hard to say.

Either way, this is a dead end.
$ locate anything
locate: nothing to report
$ grep -r "hope" /
grep: permission denied
      ~
     /|\    "I swear it was right here"
      |          — everyone, always
     / \
    
Try going home — at least that exists. Probably.
