My study lab actually sat in their seats, doing their thing, for several minutes after the lunch bell rang. When I finally motioned that they could leave L.L. made a rather shocked comment to have realized that I was in class. The kids had been so quiet she had no idea. They actually weren't even talking as they left, but only the noise of books - papers - chairs.
Frig was at school today, but in the room farthest away from mine (three floors up and the diagonal corner) after the phone call I literally ran for it. I knew he was in his study lab so it wasn't like I was going to interrupt his class. I got to his door and held up the phone. He looked at me, looked at the phone, and ran across the room to give me a hug.
