Clearly it was a busy week for cultural differences!

16. Leash laws. Maybe its just that the United States is rather berserk about their leash laws for dogs, but I've been surprised by the number of dogs that I've seen running around on the sidewalks (with an owner) without their leashes.

17. And the downside to relaxed dog laws. There is no law in the books in Buenos Aires that you have to clean up after your dog in public places. This means that you must be vigilant while walking down a sidewalk to avoid any pleasant surprises.

18. Psychiatrists. The number of psychiatrists in Buenos Aires is often the subject of jokes, but here its very common for nearly everyone to regularly go to a psychiatrist. Having dinner with my host sister and 5 of her friends, the conversation quickly turned to them talking about each of their psychiatrists - they all had one, and they all go regularly.
