Every vacation, I pack for a woman with a much more active social calendar than the one I have. She changes for dinner every night, wears different shoes depending on the angle of the sunset, and is forever finding herself invited somewhere that requires a silk camisole and, more importantly, the one bra capable of supporting it. I have never met this woman, but I continue to pack for her out of respect.

She works out. Every day, apparently! The running shoes go in optimistically, followed by the leggings and the sports bra, packed by someone who clearly has a genuine, healthy relationship with exercise. (Spoiler alert: they will not leave the packing cube.)
