Oh crap

I subbed yesterday for a teacher, and she'd left a book for me to read to them. The book has disappered. I swear to God I'd put it on her desk, but I guess I left it out somewhere. She just called, and I have no idea what to tell her. It's somewhere in her room, but I've been there once. I don't know where it is. There were three or four main areas I was at, and she says the book isn't at any of them.

Fan-fucking-tastic.

To top it off, when I saw the number, i assumed it was the computer system calling me, so I didn't give any greeting when I answered. *blushes* Now I feel like a moron.
