A person should not have to speak perfectly before being treated as someone worth hearing.

Accents, stammers, halting grammar, and unusual phrasing get quietly translated into judgments about intelligence, and the translation happens fast enough that most people never notice making it. The result is that some speakers must clear a bar of polish before anyone listens for content. The content was always there. The listening was the part being withheld.

Catch the moment your attention drifts because the delivery is imperfect, and pull it back to what is being said. Reply to the substance. If something was genuinely unclear, ask about that specific part rather than nodding through it.
