Ron had been stuck in the burrow with Bill, Fleur and a disapproving mother. He was going a little nuts. With the Twins having moved out, he had a nicer room but he and Ginny would be off flying and willingly de-gnoming the garden every chance they got just to get away from the house. He had tried to talk to Harry using the fellytone but it was not the same. They had decided to meet at Grimmauld Place so that they could go to Diagon alley to buy school stuff together and even discuss the possibilities of Horcurxes with Sirius and Lupin but Molly was clear, Ron had to be home till the last two weeks of the vacation.
