George was just flipping one of the joke coins that they stocked - it would land on whatever side the owner wants but it looked like just a regular coin - when Ginny walked in.
"Hullo love. I'm just sitting here, trying to get up the energy to try and invent something new." He stood and stretched a bit, placing the coin back in the bin where they came from. "I wanted to invent a little something for Kingston, for his birthday." George smiled brightly and beckoned his sister for a hug. "He's been asking for you, you know. I think he wants to hang out with his Auntie Ginny."
