"Did you bring a broom, Mr. Weasley?" It wasn't that she didn't trust George, or Natalie for that matter, but these brooms were all in various stages. Some could be flown but they hadn't been installed with the proper safety charms. It was one thing for her to test them out but she wasn't going to be responsible for killing George's kid. The ones that were done were in the storeroom and it would be her hide if they were taken for a joy ride.
"I'm always up to go flying but these brooms aren't ready yet. I'm sorry."
