Impertinent is an attitude or chatacteristis we have to add to incompetent, inconsistent and incontinent. Funny how the prefix converts a quality into its opposite. Funny that some people’s brains do not perceive that process. Is that because they do not perceive process or because they do not comprehend opposites — the other side, the reverse? Binary thinkers do consider pairs. But, do they perceive the relationship/connection between them?
Impertinent = does not pertain. So, it is a variant of the non sequitur. Why do we consider it a synonym for rude? Are rude folk people whose speech and responses are random? Is random the opposite of mindful? In humans is randomness the result of fluctuating hormone levels? Levels that are reset by sleep?
