Milicent tried not to come down the hall near the Room of Requirements but it couldn't be helped today, it was the shorter way to where she had to be. While the cold wasn't in a big problem to her, she had grown used to it after spending so many years in the dungons but she still had thrown on a thicker robe and scarf to be careful because of the colds running around the castle.
What she wasn't careful of was the pile up that was about to happen in the hallway. As she heard Peeves she frowned and started to speed up wanting to get away from the area as quick as she could...
But she certainly didn't see Astoria in her way from doing that as she ran into her as the girl was jumping back.
