February 14th, Valentine’s Day, is a complicated but interesting occasion. First of all, Valentine’s Day is not a holiday from work. No one gets a day off. In many countries it is observed by sending cards to your friends and candy or flowers to your husband or wife if you’re married, or to your boyfriend or girlfriend if you’re not married.

One tradition says that he wrote notes to his friends by marking on leaves and then throwing them out of the window of his prison. The leaves were shaped like a heart. Valentine was killed on February 14th and Valentine’s Day recalls his tragic death.
