If she could hear the knocking, she would have already given a sign. Such as answering the door. But seeing that she couldn't hear anything, Lenalee didn't. Simply sat there on her bed, watching the images on her PDA. She couldn't even reply to some of them. A moment later, she shut it off and placed it on top of the table, sighing. It was something she wouldn't do on a normal basis, turning off her means of communication with this world. But it was terribly depressing her already.
