Are my eyes deceiving me?

I left work yesterday with a full, unopened pack of gum on my desk. When I came in this morning, it was opened and one piece was missing. I don't want to name names, but I think someone is getting sick and tired of picking up after me. Maybe she figured after all that extra work, she deserved a little something in return.

*UPDATE - Actually, I'm shocked nothing else of value was gone. If I wanted something in return I'd have taken the CDs, the lotion, the printer, the flat-panel monitor...
