For reasons I do not understand, a couple months ago I started the experiment of handing conversations back to people when they offered them to me, and waiting to see how long until they handed said conversation back to me again. I would like to say I've been shocked and surprised by the data I've gathered, but I'm really not.
The experiment goes something like this:
Them: "Something really interesting! Let me talk for a bit about this interesting thing. Okay, I've talked about this interesting thing long enough. How are things with you?"
Me: "I'm good. I'm doing this thing. What do you think about this?"
Them: "Why, I think this way about this thing! As a matter of fact, I'm going to talk a long while about this thing that leads into this other thing. I'm going to continue talking for a while."
