"You're So Good to Me"

I listened to Summer Days (And Summer Nights!!) yester-day and noticed a small feature in "You're So Good to Me."  In the line "I know your eyes are not on the guys when we're apart," "apart" is sung with a melisma (B B A G A B).  Since the word is sung with this disjointed articulation, there's something of a sense of its meaning.
