I liked this book, although the theme has me at first seemed "easy" in the sentimental register, as a distant echo to the famous film "Intouchables". In fact, the style, clear and removed, fits perfectly to the different narrators and makes credible the speech. One might think that the novel deals with selfishness (even at the attendant, who would seek in his work to revive respect for itself), but when we come to conclusion, we see that n 'is not. It is a seemingly simple and moving reading but it pushes us to a philosophical reflection on our reasons for advancing and exister.Je recommends.
