they didn't break the mold!

Saw my mother on Oxford Street today. Petite Asian woman, lost in billowing earth tones and black. At that age, she says, it's all about comfort and hiding one's figure, not displaying it. She walks against the flow of traffic. A teeny-tiny woman. On Oxford Street. At 3 pm. Looking not at the pavement in front or her surroundings, but at a book that on closer inspection reveals itself to be "Walks in London". She even reads the book like my mother. Specs riding precariously on the tip of her nose, she tilts her head down so that her chin is almost touching her chest. Are they ALL near-sighted?
