Guilty as hell

Made some notes on a paper today. Once the paper was removed I discovered spots that evidently were done by none other than yours sincerely.
Trying to stay calm I only got warm.
They mustn’t notice.
Quickly, I tried the usual, lazy but trustworthy, way of evaporating it, I licked my fingers and started whipping as hell. The skin almost departed from my finger.
Maybe it’s not such a big thing.

A friendly finger points out the crime scene.

The spots will probably decorate my desk for some time now.
