@PavelASamsonov In my workplace, I was the *only* person in there for most of lockdown, aside perhaps from security, facilities, maintenance, and cleaning. So, basically 2 years of utter peace.
Now, about 50% or so of the people are back in the office Tues, Weds, & Thurs.
Noise levels up, productivity levels down (because they all want to chat with their mates they've not seen since last week, etc.)
