"Let's hope there are, or we're going to be the last generation," Seamus teased, smiling until his mind caught up with his own words and he started to frown. "That's ridiculous. You and Dominic can still have kids, and Susan." He paused, giggled, then started to laugh at his own mental image. He waved a hand as if to try to cancel the previous sentence. "Not all together!" He didn't know why his mind had darted down this particular track, but now he was trying to imagine a child that looked simultaneously like Dean, Dominic and Susan - and was cracking up at himself.
"'m drunk," he decided, leaning against Dean and continuing to laugh into his shoulder. He tried to let the giggles die down a bit, but then Dean started talking about lions and ice cream and Seamus started all over again. "Do lions-" He paused for breath, sucking in air and trying to form the words coherently. "Do lions even like ice cream?" He laughed again, his eyes almost watering now. "M-meat flavour ice cream?"
