I have written previously that in the Italian city of Verona, the home of Romeo and Juliet, the essence of the famous couple is everywhere. There is the home and balcony of Juliet, where everyone tries, with considerable success, to have physical contact with Juliet.
And, at one of the main bridges across the river, there is yet another tradition. Couples leave their locks on the light poles that are up on the bridges.
The story is that lovers come to Verona. They write their names on the locks and then they throw the keys into the water. That "locks" their love forever.
