The best thing would be to write down everything that happens from day to day. To keep a diary in order to understand. To neglect no nuances or little details, even if they seem unimportant, and above all to classify them. I must say how I see this table, the street, people, my packet of tobacco, since these are the things which have changed. I must fix the exact extent and nature of this change.
…… That’s what I must avoid: I mustn’t put strangeness where there’s nothing. I think that is the danger of keeping a diary: you exaggerate everything, you are on the look-out, and you continually stretch the truth. On the other hand, it is certain that from one moment to the next – and precisely in connexion with this box or any other object – I may recapture this impression of the day before yesterday. I must always be prepared, or else it might slip through my fingers again. I must never – * anything but note down carefully and in the greatest detail everything that happens.
