While the introvert is reflecting on the question (thinking first), the extrovert takes this as an invitation to fill the void (talking first). As long as the introvert doesn’t interrupt, the extrovert continues to fill the interpersonal space with talk. But as long as the extrovert talks, the introvert can’t think and stays mute. Mute means the invitation is still open, and continued talk assures that the introvert remains mute. By the time the extrovert pauses to ask, the introvert’s head is pounding and he or she just wants to get out so she can think. The extrovert just assumes the introvert had nothing to say, and moves on.
