"For me, humour is an essential characteristic if you want to stay, not only sane but also happy. Humour is somehow the instrument of the light-hearted. Humour can make unpleasant truths bearable and edible. I think that sarcasm should be used with caution. I never wish to offend, only to move. On the other hand, I actually don’t believe that you can insult someone, as you have no control over their mind, and that’s something completely different."
