What the heck??

Something kind of weird has happened.

Remember when I said that I found that ring of metal in my food? Well, me being a weirdo I kept it. I put it in my top drawer of my desk in the organizer in a slot that was just the right size for it.

Today I noticed it was missing. What the heck??

I have other stuff in my drawer that I suppose you could consider worth stealing, like a stapler and an exact-o knife. But why a random circle of metal?

Did someone take it because it actually has some value that I don't know about?
Did someone take it so I wouldn't sue the school because I found metal in my food?
Either way, that means someone went through my desk.

Or am I just crazy and I forgot that I moved it somewhere else?
This is highly likely. I can be very absent minded. But if so, where is it?
