Welcome to Hive. I especially loved the parts where you described Camagüey; you brought the city to life in my mind. Your childhood memories and your grandfather's place in the story made the writing even more heartfelt.
Also, if you could mention how you found about Hive, it would be perfect. Tagging the person (if there is) would give the credit the deserved too.
I invite you to explore other communities you might like that are part of the OCD Communities Incubation Program. Check out all the communities, read their rules and post in the one that fits your content.
