I think I understand now why some of the most beloved writers were known for being drunks. Writing something that is true puts a writer in a vulnerable position. The alcohol helps to tranquilise that fear that comes with exposing oneself.
This is the first thing I've written in a very long time that I've been able to publish for an (invisible/non-existent) audience. The two glasses of pinot helped. I had better not make a habit of this.
