Do you always speak loudly as possible? That makes about as much
sense.

No, it does not. I can easily and immediately assess the level of
ambient noise and adjust the loudness of my voice in consequence. I
cannot immediately assess the vocabulary of the person with whom I'm
communicating, and so I cannot know whether it is larger or smaller
than my own.

Mental capacity has something to do with your ability/inability to
adapt.

Yes, but intelligence is not prescience.

You suggested Gary H has a limited vocabulary.

Where?
