Respect the Divide
This person’s coworker always puts their shoe underneath the divide between cubicles and encroaching on said person’s space. So, they decided to get even. As you can see in the photo below, they put tiny googly eyes on the toe of their colleague’s shoe. Revenge is a dish best served silly, I guess.

We wonder how long it took the googly eye recipient to notice what was done to their shoe. Did they waltz about the office all day to snickers and secretive glances? Chuckles and pointed fingers? Chances are the folks in this office collectively have a great sense of humor, so no harm was done. No harm, only googly eyes.
