I think I used to work in that office. Man, that is emotion-grating writing. I salute you once more.
Tiny note: I’d swap “that” for “and” in this sentence: “Someone threw a mouse that took out an ‘Exit’ sign.” to avoid the implication that the mouse had taken out the sign and was being punished by being thrown.
I like the writing, I felt there, in this crazy office where the only person at home is the already-crazy one! You take us to strange places… excellent! Do it often!
