Lo Siento, No Hablo Español
Everyday, by 10 in the morning, I run out of Spanish (I come in contact with the outside world at 9 am, btw). I thought I would be able to get by with my knowledge of the language from grade school Spanish classes.
There are hundreds of companies offering Spanish classes in BA. From group classes to private tutorials. Competition is quite tight, which is why many of them offer extra-curricular activities like tours, wine-tasting, tango lessons, etc.
Spanglish, a language exchange group provides a venue for foreigners to mingle with locals and practice their Spanish in a speed dating setup. You get to chat in English for five minutes, then switch to Spanish for the next five. It has become extremely popular, recommended left and right by travel magazines.
With all these options, saying “Lo siento, no hablo español” is simply mierda.
