Final answer:
Reyna's father leaves in search of a better life, a common reason for migration, while Reyna and her family stay behind due to logistical challenges or hopes for a future reunion.
Step-by-step explanation:
Reyna's father leaves Iguala for el otro lado (the other side) for reasons similar to those that have compelled countless others to migrate: he is escaping danger or seeking a better life. Despite numerous potential dangers and challenges, the hope for a secure and prosperous future often outweighs the fear. This is a common theme throughout migration stories, where individuals or families make the tough decision to uproot their lives in search of better opportunities elsewhere. In Reyna's case, her father's departure may have been motivated by economic necessity, the lack of job opportunities, or other factors that have made life in their place of origin unsustainable. Reyna, her mother, and her siblings remain behind possibly because of logistical challenges or the hope that the family will be reunited in the future once the father has established himself in the new place.
