lost or stolen?

I hate to say this. My Muji sketchbook was lost or worst, stolen.

Last two days, I was still hopeful it would appear on the following day just like some of my other demo pieces or personal items I used in my class. But this time, my Muji sketchbook was lost and I believed it was stolen. It was last saw at the computer lab on the 6th level. I left it in the studio at 5th level during my class on Thursday, 8 Dec 2010 from 3 to 6pm and one student last saw it at around 6pm on 6th level computer lab. Emails were sent and words got around but I never saw my sketchbook again.

I will be staring at you all the time since my self-portrait was on the hard cover!
