This is so strange. I work in a small organization (have my whole career), and while we're not all friends, we are all very familiar. I know my coworkers pretty well, and have gone to several of their houses for holidays and birthdays. This kind of distanced and passive grief is like horror story to me.
I've gotten an offer to work in an much larger organization, but this sort of throws in to focus what a big change that would be.
