I like this. My favorite parts are the 4th and 5th "stanzas," if that's what you want to call them. That repetition of "leading me" is really nice; I don't think it would have had nearly the same effect if you hadn't repeated it. Nice choice. :) Lovely piece. Keep writing! :)
"Uh hi." It's always funny to hear how awkward people sound when saying their answering machine recording. They must feel like they're talking to themselves.
"Leading me, leading me, into the ocean." This stanza was my favourite. It's almost as if the speaker repeats the word 'leading me' because she almost can't believe how mesmerizing the ocean is--causing her to lose her train of thought.
"I hum back." Brilliant line. The speaker hums along with the 'ring' of the phone--connecting herself with the world.
