Today marks the ninth anniversary of the attack on the French satirical magazine Charlie Hebdo.
It was a shock for us at the time and we suddenly realized that even humorists - people who put their finger in the wound and use humor to draw attention to the issues that concern them - are now under attack.
Not everything can be said and not everything can be drawn. Not because it means bad publicity or the loss of followers, but because it puts your life at risk.
This was an attack on artists and anyone who tells jokes. It was an attack on the free world and everyone who wants to live in it. We will not forget this and we ask you all not to either.
