I still think that there is an insanely HUGE niche not being filled in this city.
WANTED: Spanish speaking girlfriend.
WANTED: Spanish speaking boyfriend.
I even suggested that there should be an intercambio dating service at the desk of the language school where I first took lessons. Maybe I'll talk to the chicas at Spanglish. It's such a no-brainer that it's amazing that there isn't something already.
(I'm sure some of the yentas in Once, Almagro/Abasto, & Belgrano already have a pseudo-official service up and running, but I think theirs might be a little more closed that what I'm talking about.)
