22. Buffets. You know that pesky health-code regulation that doesn't let you reuse your plates in buffets - well that doesn't exist in Argentina! This was a pleasant discovery since I'm generally annoyed at having to keep using different plates; however, it also meant that even if you wanted a clean plate for a second helping you couldn't really get one...

23. 8.5 x 11. Now here's one that has continually surprised me - paper is a different size in Argentina. Its taller than our paper, and I have no idea why. It makes it slightly frustrating when you're printing an essay from Word and the margins just don't quite work right when printed on the taller paper.

24. "Your midterm is a public document". One of my professors reminded me of that today - I haven't gotten a good explanation on this, but I've been told that any test or paper written in the public university is considered a public document. This parallels the idea of public grades...

25. How'd you do?! We all know those pesky kids in class who ask you how you did on a paper or a test just to see if they did better. Well here you don't even need to ask! In some classes grades are emailed out to the class, posted on the wall, or the best yet, read out-loud as if it was roll-call (which is what happened in one of my classes). I always took for granted how secretive we are about grades in the states, and how private we generally like to keep that information. Its very normal here for people to ask what you got on an assignment - don't think I'll ever get used to that one.
