People make cities alive.
I remember going to Paris with my mother and not wanting to spend much time in museums. Not because I was not interested in art, but because the real rarity for me was the moments outside. Cities are made of people, which share a common culture and, at the same time, have their individuality. You may go to Rio de Janeiro and see people playing “altinha” at the beach, or Italians drinking espresso and sharing ideas loudly in a bar in Italy. Or go to New York and see things you wouldn´t see anywhere else.
These moments are art.
