"That's an idea." Harry said, considering, before frowning slightly, a thoughtful expression on his face, before a corner of his lips quirked up. "Jello might break apart. And maybe worms really are ... gummy." He couldn't say he knew much about the way worms tasted.
Harry wasn't so much oblivious to the looks as he ignored them. They were easier to ignore because he had a feeling that people were looking at him and Ron because of the brooms and not because they were Ron Weasley and Harry Potter. And that actually helped in further lifting Harry's already cheery mood.
When they reached the roof, Harry grinned at Ron in return. "The twins finally beat it into you?" He knew that the Weasley's tended to play against each other. Harry was certain even his skills would sky rocket if he had to practice with the Weasley twins sending bludgers at his head all summer. It would have quite quickly become a matter of survival.
