Visiting someone’s house
It might be polite to bring a little gift, such as wine, chocolates, or flowers, when visiting Colombians in their homes. People frequently chat with onlookers while sitting on their porches or verandas. Close relatives and good friends can drop over for a visit without prior warning. An invitation is typically anticipated in other situations.
It is common to serve coffee (tinto) to visitors while they are there. Turning down a home invitation is seen as being unfriendly. A rejection could be construed as a lack of interest in developing a relationship with that individual, as such an invitation is typically sent in an effort to form a personal bond. Saying you won't be available on that particular date and then attempting to reschedule is OK. If you are not invited, stay out of other rooms and areas of the house such the kitchen, studios, and bedrooms.
