The falling leaves look like God's confetti from some divine parade.
If the leaves are confetti, then she's on street sweeper duty, raking, raking, raking. She wonders under what circumstances God would arrange a parade. Would there be a brass band, New Orleans-style? Ticker tape, as well as confetti? Perhaps someone would be throwing candy. Would there be floats, manned by angels waving majestically? She decides she'd like to be at that parade, even if only as a humble street sweeper.
