Happiness is… … being told by your dermatologist the week of a big party that your cancer scar is not ready for another round of lasering, setting the stage for scab-free socializing.Happiness is a borrowed Roberto Cavalli dress and Fendi bag. And looking much, much classier than you planned for the Calgary Polo Club President’s Ball.Happiness is being able to wince your way to the car an hour later, where you have a pair of backup shoes, after realizing your feet are not yet ready for high-heeled prime time.Happiness is also no shoes at all. And wearing white after Labor Day, because games continue through September at the Calgary Polo Club.
