Memories are killing

«So you must not think of certain things, of those that are dear to you, or rather you must think of them, for if you don't there is the danger of finding them, in your mind, little by little. That is to say, you must think of them for a while, a good while, everyday several times a day, until they sink forever in the mud. That's an order.»
in "The Expelled" (1954)
