The library was generally a comfortable environment. Sybill knew that she was always more than happy to be in the library to study. The common rooms were comfortable as well. She found Hogwarts comforting period, really. Glad that Georgia was already there and waiting, the seventh year was looking forward to getting some chatting done and whatnot.
A smile covered Billy's face as she studied her yarn and took a moment to find the end of it, situating herself. "Well, that's good. I suppose I arrived just in the nick of time."

Sybill instructed, doing so automatically with her own hands before holding the hook up to show her friend.
