You really must try to understand your own fatuous points cobyloon before trying to turn them into something they could never be. If I spot any of your favourite stereotypical bogeymen entering the bookies, St Pauls, Rock concert, etc. etc. I will certainly be concerned regarding the reason for the 'visit'. The problem to me seems to be that we have collectively ignored the reason for the many 'visits' we now seem to enjoy.
