I wrote and recorded this song years ago and hadn't thought about it in some time until I read a post that Mindwolf made titled Nothing Personal: The questionable Myers-Briggs test.
The song is titled the Sanguine because that is the personality "style" that I was assigned back when I took the test. I took a simplified version and fell in love with the word "Sanguine".
It comes from the latin word for "blood" and has an interesting path to MBTI. It was thought that the more gregarious, outgoing and social people tended to have a more "ruddy complexion" and therefore more "blood" in their cheeks. That is where the description of someone that is outgoing being "sanguine" comes from.
Anyways, enjoy the song. It was a fun one to write and record.
