High Five: 5 love traditions you've probably never heard of

Just like Valentine's Day, Juliet's balcony in the Italian city of Verona is a clever marketing coup.

Still, tourists keep flocking to the location, leaving letters at her doorstep in the hope that it will bring them luck.

According to a German custom, young unmarried men erect a tree in front of the house of the girls they're in love with on May 1.
