Nouns, prepositions ... pronouns, articles: they're all the same, right?

"I want you to keep an eye on that one. Billy Manolo. Works at the yacht club. Things have been missing. Manager had to dress him down last week, threatened to fire him if things don't improve. Boy is a hoodlum. No good."

Theodosia stifled a grin and wondered if Booth Crowley's sentences were always this staccato and devoid of nouns and prepositions.

Sigh.

Neither nouns nor prepositions are missing from this sample of Crowley's speech. Pronouns, now, they're missing. And so are articles. Even, if you're a stickler for complete sentences in speech, a verb (in the last fragment, 'No good.').

Sigh.

The writer (Laura Childs) didn't know better. Her editor didn't know better. And the character allegedly earned a good living for fourteen years in advertising after having "excelled at English and composition" in high school and gaining a liberal arts degree, so she's not supposed to not know better.

Or maybe they just don't, any of them, care.
