Poisson D'Avril

April 1 - April Fool's day, or as the French call it Le Poisson D'Avril. The concept is the same - play tricks on your neighbour, but the real focus here, revolves around putting a fish on someone else's back. According to the kids, this is hilarious! The girl's carefully hand crafted fish were "secretly" put on our backs a number of times this evening, followed by an outburst of laughter. We played along, ha ha ha, but wondered.... at what age (if at all) in France does this stop being funny?
