20 years ago, very few people were talking to (by?!?) themselves while walking around the city.
And most of the passers-by were tempted to call 911 because they considered the ‘talkers’ had forgotten to take their medicine.

Nowadays, when quite a lot of people walk around speaking blindly – to a naive onlooker, nobody cares anymore.

As in nobody cares to check whether the ‘speakers’ have any ear-plugs stuck in their ears…
