Dave had been eating his food when the girl tried to work up a crowed from the other Gryfindors when it failed, [i]"Ouch, rough crowed."[/i] he thought to himself. Feeling a little peeved at his house, Dave sat up and said "And you call yourselves Gryfindors? I haven't seen such a sorry sack of kittens since I walked off the train with the Slytherins!" With that he walked towards the girl from before, who was practically burning with embarrassment. 

Sitting himself across from the girl from before, Dave extended his hand and introduced himself. "The names David, but just call me Dave. Sorry these "Gryfindors" put you on the spot." He concluded with a sympathetic smile.
