Going back to your point about, errr, ladies of the night, Paul. We once took my Dad to Portland Street in Manchester to catch the Warsaw bus (Honest!) It was in the early hours and on seeing a very scantily clad yound lady he suggested that she may be lost or waiting for a lift and suggested that I should go and ask if she was OK.

Have you any idea how difficult it is to explain sunch things to an ageing parent? :-D
