Given the number of students at a world-leading university who appear to be incapable of reading the bit of the email that says "thank you for logging your positive LFD test, please book a PCR test" or say they haven't been on university premises and then when you email them to confirm that they say "well, I was only in the library", I also seriously doubt the existence of common sense.

I can work from home, at least, but I am utterly fed up with having my personal space taken up with work.
