I think both writers are very exact with language. We see Hal using 'thee' and 'thou' pronouns to address Falstaff, indicating a certain standoffishness (I think). Then again, Falstaff is not one for social conventions, and addresses the Prince informally. Shakespeare has the added burden of working in iambic pentameter. Or at least the noble folks talk in iambic pentameter. Falstaff and other low borns talk more in regular relaxed prose. Hal tends to speak in regular prose when he's with the guys, but in more of a formal iambic pentameter when he's with the other nobles.
For example:
The King:
"So Shaken Are We, So Wan With Care."
da DUM da DUM da DUM da DUM da DUM
An iambic foot is da DUM. The stress is on the second syllable.
Iambic pentameter is five iambic feet in a row:
da DUM da DUM da DUM da DUM da DUM
Presumably Shakespeare's audience was more in tune with this poetic aspect of the Bard's writing. I'm kind of tone deaf towards it myself. If you force yourself to read it aloud, the rhythm of iambic pentameter is more obvious.
