I sometimes notice myself engaging in conversation in a way that feels off.
One thing that feels related: I frequently rely on canned phrases. I've said these bits a hundred times. Usually these are simple reactions, like "That sucks" or "That's cool" (though not in those words). I suspect this is pretty common. People rarely point this out.
This isn't bad in itself. It does rhyme with perfunctory conversation, which would be bad as an "only food." I have a sense that more is possible. I'm reminded (maybe spuriously?) of attraction, aversion, and indifference. I'm also reminded of practical social advice to give people more to go on than a simple reaction, and to ask questions that go beyond like/dislike. I remember and use that advice from time to time. Why not more?
