Earlier quoted context omitted.
It's not a gentle push though. It's setting up a group pressure situation that is definitely gonna make introverts feel uncomfortable (by a probably extroverted person that may genuinely not understand what they're even doing in that regard as it'd feel natural for them). Now I understand that with remote work there may not be enough space for chit chat. But there are other ways than a forced group pressure situation…
I thought feeling compelled to make up a story like a dead cat would be over the top, I'm so sorry that actually happened. I don't quite get the difference between a blocked off time for chit chat and the way the manager asked for it here but totally, being forced like you have to say something you don't want to sucks.
I guess the difference is the same what I mentioned about stand-up changing: The team decided to do that. It wasn't a manager saying that's how we do things now.
EDIT: I also just realized you gave out condolences. See if I was in the situation from the article I might not be able to quickly come up with something fake and I'd instinctively just mention the cat thing (coz I don't want to be the guy that gets shunned). And then the next few weeks are gonna be very uncomfortable coz people will keep mentioning it.
