Primo Levi said this quote
“ The memories which lie within us are not carved in stone; not only do they tend to becomeerased as the years go by, but often they change, or even grow, by incorporating extraneous features. Judges know this very well: almost never do two eyewitnesses of the same event describe it in the same way and with the same words, even if the event is recent and if neither of them has a personal interest in distorting it. ”
