Seamus and Dennis and open (early)
Seamus raised an eyebrow and then his face squirmed into an exaggerated expression of disgust. "Eeew," he cried. "No! You're like my brother! And Dominic's like my step-brother, or something. Stop it! If you two ever hook up - or have ever hooked up, I demand not to know about it!" He stuck his tongue out and added another "Gross" for good measure.
He watched as Dennis fawned over the ice cream, grinning. "Did I?" he asked, genuinely ignorant of the geographic origins of his various ice cream choices. "I just picked out what I liked from Florian's and Honeydukes." Distracted from his presents, he bumped his hip against Dennis's as he moved closer to the table. "Look at the sprinkles! Some of them are flavoured." He gestured to the brown chocolate flavoured ones.
Satisfied that Dennis was capable of making his own ice cream, he returned his attention to ripping the wrapping paper and screwing it into a ball. "Wow!" he exclaimed, shifting a bowl of shamrock sprinkles to make room. "I have no idea what I'm going to do with any of them, but they're great! Thanks, Dennis."
