Today is Sant Jordi!!!
Here a bit of the legend:
In Montblanc, there was a dragon attacking the kingdom. Scared to death, the inhabitants decided to give two lambs every day to the dragon to satisfy its hunger and prevent attack on the village. But when the animals became scarce it was decided to send a person, chosen by drawing lots, and a lamb. One day a princess was chosen by drawing lots to accompany the lamb. On the cave of the dragon, the princess found a knight of the name Jordi (George) and he slew the dragon by stabbing his sword into it and rescued her. From the blood that flowed from the lifeless body of the monster was born a red rose which the gentleman handed to the princess.
On 23 April, since 1926, the main event is the exchange of roses and books between sweethearts, loved ones and colleagues. Historically, men gave women roses, and women gave men a book to celebrate the occasion – "a rose for love and a book forever." In modern times, the mutual exchange of books is also customary
