Small Caribbean islands have a high bs to reality quotient because the level of dependency is very strong. In a larger country you dont have to pretend you care or like someone unless they are your boss, your sole client, or in a position of immediate influence on your life.
Its a refreshing freedom that would eliminate many a 'dear friend' here in the Caribbean.
There are however a large amount of decent people who simply want your presence. These people are the elders in our society. They sit alone in many of our houses, needing someone to interact with, argue with, and share with. They just need your time.
If you live in the Caribbean (or anywhere), find an older person in your community and call in on them once every often. It'll help. Honestly...
If you spend your life interacting with people whose main need is to have their egos fed so that they can help you put food on your table, then....you will have many an imaginary friend.
