Ive been listening to an 80s station at work and a song lyric raised a flag in my brain.

80's Hit Song by Animotion "Obsession": You are an obsession You're my obsession Who do you want me to be To make you sleep with me You are an obsession You're my obsession Who do you want me to be To make you sleep with me

I feed you I drink you My day and my night I need you I need you By sun or candlelight

And from an earlier journal entry:

"How do I love thee? Let me count the ways..." by Elizabeth Barrett Browning (1806-1861)

I love thee to the level of everyday's Most quiet need, by sun and candle-light.

I think its likely they are referring to the poem.
