Two things that really puzzles me about Argentinos is the way they burst out from e.g. shops into the street as if they were all alone in the world.
The second puzzling behavior - or rather non-behavior - is that many Argentinos seem to be unable to see things. These two may be related.
I have often been sitting in a car or bus with Argentino friends, and say "Did you see that ñandú (or Ford TinLizzy vintage car, or a man in green polka dot coat, or ..) and they haven't noticed it.
One day I was carrying a beam (una viga) home on my shoulder. Its dimensions is 220 x 25 x 7 cm and it is white, easily visible half a mile away, and yet a local man banged his head into it as if it was invisible.
I have a feeling that a stray white elephant with large red bulls eyes painted on its sides, roaming the streets, wouldn't be noticed either.
At first I thought this might be a genetic trait, but giving the phenomenon some thought I realized, that not only were some 60% af the population born elsewhere in the world only 4 generations back (not enough time for a genetic trait to spread to a large part of the population), but also that I experienced exactly the same in Turkey 20-25 years ago.
Any ideas?
