Gaga posted on her Instagram two days ago a shot of her in a bucket hat, wondering why they are popular. I like to imagine that, as she sashays out of her hotel and glamorously waits glamorously for her car, she is still plagued glamorously by the question. Haunted by the hattery. Besieged by the bucket. “Why?” she is thinking, glamorously, as she reaches for the cool, comforting, grounding metal of the banister, as if her hand will close around it and, with it, the answer.
