This quote by Jacques Chirac is a funny way of revealing his dissatisfaction in somebody's failure to make the most of a possibility to remain silent. It implies that the person in question had the opportunity to avoid saying something that would have been much better left unsaid, however rather selected to speak and thus missed out on the chance to remain peaceful. This quote can be interpreted as a reminder to think prior to speaking, as words can have a lasting impact and can be difficult to reclaim. It also functions as a warning to be conscious of the repercussions of speaking without considering the possible consequences. Chirac's quote is a pointer to believe before speaking and to be familiar with the power of words.
"The opportunity to create a small world between two pieces of cardboard, where time exists yet stands still, where people talk and I tell them what to say, is exciting and rewarding"
"To be really great in little things, to be truly noble and heroic in the insipid details of everyday life, is a virtue so rare as to be worthy of canonization"
