Chris Gaskin was a little surprised when the waitress taking orders at a family meal gave her a beaming smile.
She was even more shocked when it was followed by an invite to her wedding reception. The silence was awkward and felt like it stretched to eternity. But this was no stranger making a social gaffe – she was a close neighbour with a genuine offer.
For Chris, 65, from London, it could have been her best friend, King Charles or Barack Obama – she would not have recognised any of them because she is living with the neurological condition prosopagnosia, or face blindness. It means faces, even those of her nearest and dearest, do not register.
