Hola Dan,
Créeme, es un placer para mi!
I love my country, of course there are things I dislike, but mainly I found it fascinating.
I wish that explaining cultural things about my country was as easy as A, B, C. But it is a little bit more complicated. The US and other big countries will understand, they do, eat and talk a certain way in the west, and it is a totally different story on the east, central, north, south, etc.
Same goes for Mexico, I cannot name a national dish, because, what applies here in the northwestern part of the country, doesnt in the southeast. Customs in Mexico City, are different than the ones in Monterrey. Beer prefence is different in Sinaloa, than it is on Veracruz. Regional music in Durango is totally different than the one in Jalisco. Accents are different, physical traits also vary, a taco in Sonora is not the same as a taco in Yucatan, they could both have the same tortilla, but the filling will be different. Even if they are mostly the same, maybe the salsa is a different color, the beverage you drink with it may change, the condiments or garnish may be diferent....AND THAT IS WHERE THE CULTURAL MAGIC RELIES, DIVERSITY, AND THAT IS WHY I LOVE MEXICO, because even with all those differences, we have things in common, we honour the same flag and national anthem , we speak the same language, we like our food and our beverages, we like to party, we are warm , we love music and we like to dance, it doesnt matter if it is a Mariachi from Guadalajara, a Trio from Xalapa, playing son jarocho, a norteño band from Reynosa or a Rock band from Mexico City.
Sorry for the long post hahahah!
