My thoughts went: "Is that a plane coming in really low? What is that? There's no plane sound. Oh... Earthquake!!!" I was chatting with cj2017 at the time so my immediate reaction is actually documented:
cj: it even annoys me when Sarah's at the con and comes straight out with her name and details about John. She wouldn't do that. They made a point of her NOT doing that in Good Wound
me: and yet you have no problem with Sarah not having the brain power to figure out that a hole saw bit makes holes in wooden birdhouses?
cj: no cos that was a daft ep in general, this one was trying to be SIGNIFICANT
me: oh yeah I do hate that scene at the con
me: holy shit
me: I thinkwe ust had a fucking eathquake
cj: WOAH, you okay?
me: my whole house fucking shook
me: that was cool
I then went to check on the man, hoping he'd woken up so I could see if he thought it was a quake too. He was awake and was trying to process what had caused the house to shake. He thought maybe the AC had clicked on and woken him up. When I said I thought it was an earthquake, he hopped out of bed and we checked the USGS website. Within a few minutes they had it listed and the man got to be the first person to report it from our zip code. Then we flipped on the local news and they were talking about it.
Big excitement... our own little quake :)
