Revenge may be sweet, or best served cold – but the target may not even notice. Christie Clancey’s New York Times essay,

Revenge of the Friend

humorously tells of a professional trainer trying to torture her best friend’s ex-husband when he shows up for her spinning class, with his new girlfriend.

When she directs the lothario to the most uncomfortable bike with “narrow saddle…as hard as concrete,” for thirty minutes of hellish biking to the tune of “50 Ways to Leave Your Lover,” she hoped for an exercise meltdown. Instead, he was oblivious to her ire, and thanked her for the “best workout…in a long time.”

Unless you plan to leave a horse’s head in the bed, revenge is probably not worth the effort.
