How is Colombia ?

Colombia is a tropical country, with different kinds of people, for example the people inside the country are quiet mostly

are white people in Colombia the people of Bogota are calling (Rolos) [this bit is impossible to correct:- are the 'quiet' people the same or different from the white people'? by 'calling' did you want 'called'? :) ]

(Bogota is the Colombian capital and is inside too). But if you visit the coast of the country [you don't need 'of the country' since 'the coast' already means 'of the country'] you are going to find people more outgoing that they prefer a relaxed life and for this reason these people aren't known as good workers.
