Lover

“At every table, I'll save you a seat”

“My heart's been borrowed and yours has been blue”

“With every guitar string scar on my hand”

“My heart's been borrowed and yours has been blue”

Twists the "something old, something new, something borrowed, something blue" wedding-day rhyme by redistributing two of its prescribed objects across the lovers' emotional histories, the speaker's heart as the "borrowed" item (loaned out, returned, used), the lover's as the "blue" one (sad, marked by past melancholy). The rhyme normally describes what a bride wears on her body; here it describes what the couple bring into the ceremony itself, and the swerve only lands because the surrounding song already speaks in wedding diction ("with this hand I'd let you put your name in my phone").
