Ron had gotten the chocolate torte out of the kitchen, wrapped in its box with string tied about it and moved to the Floo, ready to get going. They were late, he was sure, and it was due to him, of that he was quite certain. He'd been running late; his hair was still wet from his shower and he didn't realize that his shirt was not buttoned properly in his haste. He had grabbed a coat and with the box in his hand, he stopped at the Floo to look for his wife.
"Hermione? You ready? I'm just going to go ahead and go," he said, and with that, he threw the green powder into the Floo, stepping into the flame....and stepping out with a solid smack to his forehead.
His hand went to his head, and he winced, and swore, "Bloody hell!" he mumbled as he stepped down and out of the small fireplace into Harry and Ginny's place. With his hand still to his head, he looked about, "Hey! We're here," he said, grumbling slight even as he moved inside more, rubbing the bump that was forming on his head.
