Weather (indoors edition)

Sometimes, you might have a late-afternoon meeting that would require you leave your office in a big hurry at around 4:20.
And sometimes, the next morning, you might decide to work from home to finish up a very important project, which would mean you'd get in around 11, when the project was done.
Sometimes, it might happen coincidentally that in your haste to get to the meeting, you might neglect to turn off the humidifier that is necessitated by the fact that your office is very hot and dry.
And so sometimes, by the time you opened the door to your office, there might be condensation dripping off the window, and your office might resemble a tropical rainforest.
