This song is written from the perspective of a frustrated wife who turns to drinking after her cheating, no good, alcoholic husband leaves her. Fortunately, it's pure fiction: Holly married her drummer, Chris Coleman, in 2009, and while marital bliss is subjective, it's clear from Holly's lifestyle blog
that when she wrote this song, she was more likely to make a pâté than to go on a bender.
Holly, however, is the granddaughter of Hank Williams, perhaps the greatest storyteller in the history of country music. She told Songfacts
it's an example of his influence: "That's always been very natural to me to write a really simple song, with repetitive verses and a story. 'Drinkin'' is more in the Hank Sr. style of writing."
