Morning Scene - A Mystery

There’s something strange going on at the elevator where I live.

Each morning when I leave for work and summon the elevator, I’ve noticed that there seems to be a small item left on the wall panel – a pen, a stick of gum, a piece of candy.

This morning, it was a lollipop. A cherry Dum-Dum.

Somebody’s got a little sump-sump’n going on.

I have no idea what it could be.
