CIRCLE WITH A DOT

As an RA in college, in training every year we had to watch a video of a dorm building catching fire in real time. It was due to be demolished anyway, so was set on fire as a controlled thing, to demonstrate how quickly fire moves. It was so, so incredibly fast. And that's in a building that was entirely empty save for the single room where the used a tipped-over candle to start the fire. Do _not_ mess around when fire alarms go off. Just get the hell out.
