Azizi, it's common in the UK for men to afford women (of any class, race or ethnicity) due respect by referring to them as a 'lady' - I do it all the time, as do most of my circle of (male) friends. So, for instance, I would indicate a particular woman in a crowd as perhaps "the lady in the (specific) dress", rather than "the woman.....".

It's not an indication of belonging to the 'nobility' on the part of the woman, nor of any specific attitude towards people of colour on the part of the man, it's simply politeness on the part of the man in his reference to a woman.

Two nations divided.......etc.?
