Tis some visitor, tapping at my chamber door Only this and nothing more

Sitting in the guard bucket overnight this past weekend for a lovely boring and *quiet* shift. Catching up on reading, camera babysitting, reading stuff on writing prompts here on reddit. I keep hearing a faint "bwoomp" on the window as if someone is tapping on the glass. This not being an Edgar Allen Poe tale, I keep looking for people running around in the dark. I keep coming up empty. "Bwoomp!" the window goes. Again. This goes on for awhile, the tapping on the window, me looking for the source and finding nothing. Finally I'm looking at the window in time to see "BWOOMP!" a mouse bounces off the glass in front of my face! A feathered silent blob darts by glaring at me as I step out to look. The owl then sits across the way making all manner of avian threats and curses at me because I just disturbed his game of mouse bounce. He never retrieved his mouse, it's dead behind the guardshack. "Get your beak out of my..." No, I didn't quote Poe. That would have been too perfect. I was just impressed that an owl was amusing itself by throwing mice at my window. And that is the end of a super quiet shift on site...for once. Tl/dr: Owl throws mice at security, security unmoved.
