Reminders (Notas para no olvidar) 6 years old

Piro is a mathematician whose obsessions have been captured in three notebooks; one to keep a rigorous control over his expenses, another to remind himself of the location of the things he collects in case he ever needs them, and one more for the most important events of his life. We will use these notes as a starting point against oblivion, a journey through the lives of three generations of my family.
