I'm on a roll.
Brian was actually home when I called, but that does not help my case. He said that I repeated my command to leg it and, well, legged it out of there. He stayed - he was in too much shock to move.
He stayed there, unmoving, until another person came in, at which time he turned around and ran.
He said I should count myself lucky that I haven't heard what he heard when he turned around, just before he left the shack. He counts himself lucky that he didn't see it.
I have no information what I did in the hours between that and my wakeup in front of my computer, but I'm still looking.
