The top 4 signs that I’m currently in Buenos Aires, not Seattle
March 14, 20084. Posters for the movie 10,000 B.C. give the title as “10.000 A.C.”
3. Every time I go out for a run, I wind up in some dead-end alley amongst free-roaming dogs and boys playing soccer.
2. If you dine out and order a main course of beef, the waiter brings you a giant plate of it … followed by another giant plate of it.
1. Some bathrooms have soap dispensers like the one shown here. (Image copied from picasaweb.google.com/leahrimkus/BuenosAiresArgentina.)
Getting soap out of this dispenser was not easy. I tried everything: pushing it toward the wall, pulling it away from the wall, moving it left and right, moving it up and down, pressing on the white base…. After about a minute of this, I realized that my hands were getting kind of slippery. The yellow “soap dispenser” was made of soap.

i appreciated the soap anecdote; i've made similar (delayed) discoveries of unfamiliar objects in foreign locales myself. i once came across a shower i never did figure out.please do let us know what happens when you run out of soap. but be careful. it's entirely possible that that metal rod "tapers" into a rusty razor blade! yikes!
Imagine the opposite: an Argentine in a U.S. bathroom touching the soap dispenser everywhere to figure out where is the part that is made out of soap, and you get me! I hope you had fun in BA.
