1. You have to be careful not to get hit by a car.
Especially if you’ve been living in Europe where every driver slows down as soon as they see your foot on the road.
2. Food will be even better than you remembered.
You may have forgotten the real taste of meat, the amazing stuffed pasta of La Juvenil, Daniel’s ice-cream, the alfajores, the pancakes with dulce de leche, the chocotorta, the empanadas, the gnocchi… but as soon as you eat all those things one more time, you won’t want to leave.
