It was me. I did exit on Broadway. I was wearing a purple sweater.
But do I really look that much like my brother? I'm almost five years older. His hair is blond, while mine, especially when I lived in Seattle, is more brownish. Our eyes are different shades of blue. But the main thing--he's a foot taller than me, as in a dozen inches. Tall and thin to my short and curvy. So how did this stranger know that I was my brother's sister?
It had to be the nose.
