I'm really interested in the "Tea With Strangers" idea and looking forward to finding one, when lockdown is over, in the distant future. Semi-related, lately I've been looking for resources on how to have better and deeper conversations. I wonder whether anyone has any books that they've found helpful. I come from a very sort of buttoned-down sort of people who have trouble moving beyond surface-level small talk, and I've been trying to find ways to get people (and myself) to be comfortable opening up in conversation.
