I have been in Rosario, Argentina since the 20th of June. Since then, I have observed several differences between our countries based on observation and conversations with the people here.
I have not seen a single stray cat. There is, however, a large population of stray dogs who are so street savvy that they will wait for the crosswalk sign to change and walk within the boundaries of the crosswalk.
Services are cheaper here! A full massage cost the equivalent of 22 American dollars.
There is a large Italian influence in Argentina and for those spanish speakers out there, all "ll's" make a "sh" sound, so "calle" would sound like "cah-shay".
Everywhere you go, you can find pizza, lots of it. We went to an alleged Mexican restaurant called Club Tijuana that also served pizza. Their trademark dish here is milanesa which is similar to country fried steak/chicken with your choice of sauces, and then the locals also dollop cheese fries on top. Scrumptious, but very indulgent.
Everybody walks everywhere.
The most expensive private university education costs the equivalent of 7000 dollars per annum.
If you make 25000 dollars/year, you're considered quite well-off.
When ordering water here, you must specify with or without "gas" (carbonation) and people drink it a lot and it tastes like club soda.
There is a traditional drink here called "mate" (pronounced mah-tay), and you add what looks like coarse herbs resembling cedar pulp to a hollow gourd and you sort of mash it and apply hot water and you drink it through a "bombilla" which is a metallic spoon/straw. This is an oft consumed beverage and you are meant to bond and converse while drinking it.
There are many breaks throughout the working day in Argentina. Businesses open at the usual time, but smaller shops take a break mid-day for several hours, as well as tea time which is in the evening, and those stores will not re-open until 9 pm or so which is when most people go out to eat, but not many Americans do for fear of eating and then going to bed soon after.
Much like my experience in Japan, clubs, or boliches, are open from about 2 am - 6 or 7 in the morning. I went one time and it left me very exhausted.
