You’re trying to get your message across. Something needs to change, and maybe the impetus for the change wasn’t something negative that happened as you hear everyone suspects.

If they aren’t getting your message, saying it louder won’t change anything.

It’s not a hearing problem. It’s an interpretation problem. Maybe you should consider changing your delivery rather than getting frustrated with their interpretation.
