How often do you have imaginary conversations in your head? Not with imaginary friends, people you know. Where you think of saying something, then you imagine what they say back, and before you know it you've made up a whole conversation hardly even realising that you're doing it. Or with posts. Do you imagine posting something, then think, well, if I said that, so and so would say this, then I'd say that, etc.
I assume everyone does this but it's happening crazy amounts to me at the moment. I keep having arguments with people and then resenting them and then realising that it was only ever in my head. I don't do it on purpose and it's getting really quite frustrating. But most people do this, right?
