It's not about what you say or write but how you express it? If that is the case the emphasis is on the emotional thought from the speaker or writer?
It's the difference between saying the
right things and saying
things right.
What's most important is to say the
right things. If you say the wrong things, you're
not communicating. People won't know what it is that you intended to say. The only exception would be someone like a wife, who after living with you for decades has learned to understand your thought processes and can guess what you
meant to say. This is the difference between "I love pizza" and "I'm really hungry."
But once you've got the right things in your sentence,
then it's important to say the
things right. You have to make sure that you don't accidentally express
connotations, insults, attitudes and other
subtleties that were not your intention. This is the difference between "May I please be excused to go to the bathroom?" and "I have to go pee."
