Laudator Temporis Acti — ”Thus a small badge saying ‘Please talk to me about Salvation’ usually had the effect of ensuring a peaceful time at any party, leaving one untroubled by other guests coming up to engage one in unwanted conversation. Similarly a badge saying “No longer infectious” could usually be calculated to ensure physical space, another commodity in short supply at the more popular cocktail parties.” Alexander McCall Smith, Corduroy Mansions.
