She had this childish belief in an elaborate system of penalty and reward. Ever since she was a child, She used to hold pacts with god; she promised him things in return for small favors: moving to New York, for example, was made possible after a volunteering work with the elderly was guaranteed. For a rational woman, she was extremely superstitious. She saw signs and omens everywhere.

She tried to decipher her unexpected misfortune. She blamed it, like she always did, on her vanity.
