Existential philosophy, poetry and art - just like sadness - were all unavoidable to a tender young man in the meat works.

As a cartoonist, I am not interested in defending the dominant, the powerful, the well-resourced and the well-armed because such groups are usually not in need of advocacy, moral support or sympathetic understanding; they have already organised sufficient publicity for themselves and prosecute their points of view with great efficiency.

At the age of nine, I simultaneously fell in love with two Dutch sisters because they seemed so beautifully strange, and their clothes were mysterious and alluring - added to which, they could not speak a word of English.
