Flying back from D.C. last week, we had window and middle seats. The man in the aisle seat wore a baseball cap, a sleeveless white shirt and white shorts that revealed most of his thighs. This extensive exposure of skin was apparently due to the fact that it was extravagantly tattooed, on both legs and arms. The vast ornamentation made his baseball cap – the wearing of which I usually deplore indoors – seem almost modest.
