Hello, Mystery Table!

I came into work and for the past half hour have been walking around asking people if they know why there's a frickin' extra desk, chair, and whiteboard in my office.

Apparently somebody's moving in here?

So much rearranging it for spaciousness and productivity. End result: somebody realized it was now big enough to pack somebody else in here.

I'm sure there's some halfway sufficient reason, but I would've appreciated at minimum some sort of heads-up.
