I work in 911 dispatch, my job is talking to people, and often quite unpleasant people at that.

On my own time, fuck that noise. Live conversation kind of sucks. When it’s next based I can walk away from it, think about it, come back write my reply and hit send. Most of the time I can’t exactly walk away from a live phone, radio, or in-person conversation and say “hey, good question, I’m gonna go take the dog for a walk while I think about that and get back to you in like 10 minutes” there’s an expectation that I’m gonna be there engaged in the conversation and keep everything flowing, and most of the time that sort of urgency just isn’t needed. I want to be a part of the conversation, but I don’t necessarily have big chunks of my leisure time to set aside to just talking to people, but I can squeeze in a message here or there while I’m doing whatever else I’m doing.

Take this whole exchange for example, I saw your comment, decided I wanted to reply to that, but I had some things I needed to take care of, so I did them, thought about what I was going to say, and wrote it out when I had a few minutes. You’re going to see it when it’s convenient for you, and maybe write your own reply, which I’ll see and reply to when it’s convenient for me, and so we’ll have a back-and forth conversation that may span a few hours or even days, even though each of us only wrote a couple messages.
