Do you know  a lot of people from other Islands pretend to be Jamaican?  Jamaica is the big Island and people know the Jamaican big Island ego.  If they pretend to be Jamaicas, it helps them earn the trust and navigate. But, with their commitment to their own Island's or family's success, they win.  They never let an immediate family member down.   All of the other islands have covenanted amongst themselves to work together in unity to secure the life of any citizen in their culture. Using a Jamaican and their egos is just the collective fun of the West Indies to watch a Jamaican put someone other than his own family or himself above the Jamaican or their alleged Jamaican pride.  The other islands have functional unity.  The Jamaicans do not.
