There may also be a report on touristic-type activities undertaken around conference I am attending tomorrow.
In lieu of other content, have my thorts on this etiquette question.
We consider that if you are flaunting your precious pricey vintage crystal, you should conduct yourself in the spirit of the great lady recorded by GB Stern, who, when dining the peasantry on her estate, to alleviate their fears of spillage etc, began the proceedings by spilling a large quantity of red wine on the pristine white tablecloth.
I.e. You should yourself smash one of your pieces of crystal, with an insouciant laugh.
Rather than putting on dog about your posh possessions and inhibiting your guests. Fearfully poor ton.
