One major cultural difference here is time. People here tend to not be on time. Sometimes I think I have traveled to Jamaica! My 9:00 am class on Tuesdays and Thursdays never seems to begin on time even if she is in the building. One day she was 20 minutes late (she had an excuse so I forgive her). Classes do tend to end on time even if they don’t always start on time.
Another cultural difference with time is Dinner time. Here dinner isn’t typically served until 9:00 or later. Sometimes I get lucky and my host family eats around 8:30. On Saturdays when I have to go out for dinner, we tend to arrive at the restaurant at 9:30 and the food comes closer to 10 (service here is slower and the waiters are less attentive than in the U.S.). Late dinners seem to go against all the rules of healthy eating in the U.S. but here the people eat late and still maintain a healthy weight. Breakfast tends to be small and lunch times and sizes vary.
Lastly, going out times here are much different. Here, it is not uncommon to start heading to the clubs at 2 am. In the United States, clubs are getting ready to close at 2am. The people here stay out until 6am or later. Dancing all night and then grabbing breakfast before heading home to sleep is not out of the ordinary. Heading to bars at midnight is normal as well. Calling it quits at 4am is considered an early night. Taking nap after dinner at meeting up in the wee hours of the morning to go out is completely acceptable.
Time is a major cultural difference here in Argentina. Buenos Aires is a city that seems to less than New York.
