Heads of state sometimes gather in Port of Spain to jockey for position, with some reaching out and some more antagonistic. Often overlooked is a lesson in personal diplomacy that the entire world might take from the host country, Trinidad and Tobago. The two islands, quite different from each other, form a single country, and have the Caribbean’s most intriguing culture. People who are often at loggerheads elsewhere in the world get along just fine here, thank you very much.
