Sean is in town for a visit and to enjoy some time off from work, having over six weeks of leave remaining. He used to regularly go out to bars with his brother, but those days are behind them due to his brother's recent marriage, which Sean humorously notes as a "battle of the sexes." The bartender responds with surprise at that dynamic, expressing sympathy for Sean's change in social life.
As they converse, Sean takes a moment to sip his beer while discussing his brother's lifestyle shift post-marriage. The story he's engaged with tonight is from the book "Angel's Peak" by Robyn Carr, which adds another layer of relaxation to his evening. This suggests Sean is looking to unwind and find solace during his time off.
