This position is not an usual writing position. The woman here, Françoise, is writing in this uncomfortable position because she had a poem. And this poem was very urgent, like a besoin urgent. This is what she answered to me when I asked her: why do you write like this? Then I added: does it hurt and she said: do you mean, do the poem hurt? Of course, the poem hurts; this is why I prefer to suffer one moment in this position instead of suffering for ever and not writing the poem. I had some more questions. For instance, what about paper vs portable computer? Brown trainers? Right handeness? etc... I must confess that Françoise lost her poem because of my stupid questions.
