The patches, the patterns, the process: all are part of memories kept but not well kept. That is why the title is "a key." New series in parallel to others, just as it happens in everyday life and without grace many times. As a basis, I use the poem by Antônio Cícero, quoted in an excerpt: "To keep something is not to hide it or lock it up. In a safe you don't keep anything. In a safe one loses sight of the thing. To keep a thing is to look at it, to stare at it, to look at it for the sake of admiring it, that is, to illuminate it or be illuminated by it."
