Je suis chanceuse: Charlie Hebdo two years on

On 7 January 2015 at about midday local time, I sat down to lunch with my colleagues in the 14th arrondissement of Paris. It was then that I learnt how around 30 minutes earlier two brothers, Saïd and Chérif Kouachi, forced their way into the 11th arrondissement offices of the French satirical newspaper Charlie Hebdo.
