Cathal nodded to her gesture, because he'd probably want another beer. He accepted it with a nod and then said, "Well..." How honest to be with someone he didn't really know? Not entirely honest, obviously. Didn't want to give the impression that he was crazy or make everything too complicated and confusing.
"I've never gotten on so well with my parents," he said, taking a sip of his beer. "They're both really old fashioned and, well, fucked up in a lot of ways, and as soon as I was old enough I moved away to Belfast to escape all that toxic mess. But then I took a visit home and we had a massive spat and I decided I didn't want to even live in the same country as them anymore. So I got out, and here I am." It was the easiest way to describe how the relationship had imploded, even if some things had been left out.
"But your parents," Cathal said, gesturing with his beer and smile. "I love your parents, they're fantastic."
