Having spent three months in Oregon and Las Vegas, I have become so much more aware of the cultural differences between the north American first world and Mexico.
The first Americans were independent and forward looking. They were looking to expand and were aggressive. Their primary value is freedom and personal space. Mexicans on the other hand were subjugated for hundreds of years by the Spanish. Their primary value is respect.
Whenever a person enters the space of a Mexican individual, for example getting into a taxi, unless you greet them they will feel you are rude. Instead of just jumping in and issuing an order you say “Buenas Tardes, Senor.”
While in a restaurant, any time you pass by a table you say “Buen Provecho.” Any time you want to walk through or pass by people you say “Con Permiso.” Needing a waiter to come to your table you call “Joven!” (Young man) or Senorita (young woman.)
The smiles you get are warm and welcoming. It’s a lovely way to live.
