On Feb 8, it will be six months since my friend's car crash. This is a crucial date because according to the doctors, if a patient is going to make a meaningful recovery after a coma, it will be apparent within this window of time.
It is also the point at which the doctors will carry out further tests and decide whether or not to transfer him to Le Grand Feu - the renowned hospital unit at Niort where the real work of rehabilitation and reeducation is carried out.
My friend needs to give medical staff a sign that that he is in a position to benefit from Le Grand Feu, that he is able to progress to the next stage.
So far, he hasn't. He speaks only a few words a day and moves very little, although I am convinced that he can understand two languages.
'But there is hope?' I ask his (wonderful) psychologist this morning.
'Yes, there is still hope,' she says.
'Come on,' I think to myself, silently willing him on. 'You can do it. I know you can.'
