On her daily route delivering laundry in her working-class neighborhood in southern Mexico City, Maria Carlotta Santa Maria, or Mari, as she is known, seems to know everyone: the mailman, the woman on the corner selling salty nuts, and her favorite greetings are for the guys at the corner gas station.
Mari is the kind of person that can make this inhospitable and overwhelming megacity seem almost small and friendly. But as a single mother, she says raising her 10-year-old daughter Jimena alone hasn't been easy.
