I rarely drink during the week, well unless there's a holiday, or I'm off, or there's some occasion, or friends get together, or we're celebrating the fact that it's (insert weekday here).
As I've said, I work overnights and this week my two days off happened to fall on Tuesday night and Wednesday night. A friend asked if I'd like to stop over for a couple of drinks and by virtue of some twisting of my rubber arm, I agreed.
