"Even more better," Seamus insisted, stubbornly, knowing he was being grammatically incorrect but knowing also that it was part of his charm. He gave Dean a weak self-deprecating smile. "Not so much the being old and wrinkly part, obviously." He couldn't really imagine either of them old, but they had a lot of years left before they had to find out what it was like. Seamus didn't even think of his mum as really old yet. "But not feeling like we're holding on by tooth and nail..." Not that Seamus felt that way all the time, but he liked to imagine he'd be settled in his 40s. Not so... all over the place. Even if he ended up 'settling' as an eternal bachelor.
He groaned when Dean failed to miraculously understand the reference. "You know," he insisted. "Like..." He made a smaller-than-usual gesture with his free hand. Whatever it was, wherever he'd learned about it - Dean must've been there too. They practically shared a brain sometimes, so if Seamus knew something he assumed Dean knew it too - unless it was something pub-specific like the exact cost or stock-level of butterbeer. He gave up with a sigh. "It wasn't a compliment. It was a comment on how we are, as Susan would say, practically joined at the hip."
