What seems to still be eluding the issue here is the true content of what is being said. I think most non-Fe understand to some degree what the Fe wants from them, but the question is one of energy to extrovert this consistently.
If you are an introvert who has the energy play social ping-pong all day, I am truly happy for you, but for some introverts this is not realistic and there doesn't seem to be a way to tell *some* Fe this in a way they will accept. They continue to try and "help" the introvert "get over" their "problem" by continuing to explain and at times demand their social rituals.
Even in this thread there are comments that there needs to be smiling and it better not be fake, because no one wants a fake smile or that is going to put people off and that hello must be said in the exact right and sincere tone with the exact right look to the face.
