You don’t need to tell people they’re being boring.

where did you get that from? I don’t tell them directly they bore me, that’s what I think as I imagine leaving.

You can just leave and not interact and thus not hurt their feelings, and thus not have conflict with people.

actually that’s not true: if extrovert A says something I don’t care about, I wait patiently till he ends it and I leave, he will feel offended (an extrovert explained this to me). I don’t understand it but apparently it’s like this.
