I wonder. I didn't hear anything, but it could be just as likely that nothing happened in the proximity of the library, that's all.

[ If it did, though, it'd mean that the library has been really popular overall this week. ]

Your own room... it would have probably been the most secure place to be, had we known before that this would happen. But hindsight is 20/20. The best we can do is be wary, that this won't happen again. At last, not to our own selves.
