Wow, Javier... it's in Spanish! I will need to get out the translator. But one of the most interesting aspects in learning a new language is exploring common rituals, marriage, school, dating, eating, sleeping, believing, etc, and seeing what is the same and what is different. I love that stuff!
Since you are in Peru, I believe I can end my post with something like, With affection : ) I love the way South Americans are relaxed, gentle and friendly in their salutations. I am affectionate and enthusiastic by nature, but many Americans are uncomfortable with "A hug and a kiss" at the end of their emails!! : (((. But that's me! It doesn't mean anything more than a nice way to say goodbye, until later!!
