Casey Spelman, of Indianapolis, was visiting friends in Chicago and spotted a blind man having trouble hailing a cab. Without a word, Spelman split from her friends, walked over to the man and tapped him on the shoulder.

“Do you want some help getting a cab?” Spelman asked.

“He said, ‘Yeah, you sound pretty, so cabs will probably stop for you before me,'” Spelman recalled the man joking.
