I'm a librarian who loves anime, manga, and reading a wide variety of genres.
[Non-book post ahead.]
The HVAC system at work is being cleaned for possibly the first time ever (a coworker of mine who has been here for more than 40 years can't remember the last time this was done). They started with my part of the building, and there's a noticeable difference already - the air smells fresher. I shudder to think of what we've all been breathing in on a daily basis up to this point.
Unfortunately, it also seems to have lowered my office temperature by a good bit. I've been freezing for the past two days, and no one has been able to fix the issue yet. I'm wrapped in a blanket, I've broken out the tiny space heater that I'm not technically supposed to have, and I'm about to put on some fingerless gloves. I think there may be several coffee breaks in my near future.
