"No good sittin' worryin' abou' it," he said. "What's comin' will come, an' we'll meet it when it does."

Hagrid's comment from Chapter Thirty-seven reflects the fact that wizards must simply wait for Voldemort to make his next move. It is appropriate and refreshing for it to come from Hagrid, because although he does not have Dumbledore's eloquence or trained wisdom, he is speaks as someone who has undergone accusation and hardship. He, of all people, should know that the most terrible things can never be predicted. This comment allows the characters to relax during a calm summer, letting life continue, but acknowledging that it will not be perfect, especially not in the near future. This line offers a realistic closure to one stage of the constant battle against evil in the wizarding world.
