Interestingly enough, I find were having more of these conversations working remotely than we did in the office. I think part of it is that using MS Teams other people are a lot more accessible, just drop into the chat and leave a message. If they are busy no probs, if they aren't then they will reply and we talk about whatever. Sick of typing, drop into a voice or video chat. Want to talk work, then it's easy to share a screen. A lot easier than looking at a screen over somebodies shoulder.
Whilst I do miss going out for a coffee or some such, I'm finding that I'm actually enjoying the social side of working remotely a lot more than the forced socialisation that was occurring physically in the office.
