"A Drop of Ink in a Glass of Water..."

As many of you know, I am a die hard fountain pen user.  I am also a huge fan of the band "The National."  So often times I have the music and lyrics going through my head, because that's what music does to me.  To save money by not buying ink cartridges for my pens, I refill them with ink from bottles.  I have a special blunt ended syringe, and I suction the ink out of a bottle and then inject through the opening in the cartridge.  I do this a lot because I write a lot.  So the other day I was cleaning my syringe after filling some cartridges.  I am using purple ink in two of my fountain pens.  And then the lyric came to me from the National's song "Green Gloves."  So I took my syringe and dropped some ink into a glass of water.  Here is the result.  The lyric “like a drop of ink in a glass of water” is associated with the song “Green Gloves” by The National, from their 2007 album Boxer. The image is a phrase often used to describe how the music or feeling of the track spreads and deepens. The metaphor fits the band’s style: emotions slowly spreading and darkening the mood, like ink diffusing through water.
