St Valentine talked to the daughter of the prison guard who helped to keep up his spirits. On the day of Valentine's death he left a note to his new friend, thanking her for her friendship and loyalty. He signed it 'love from your Valentine.'
That note started the custom of sharing messages of love on Valentine's Day, February 14th, the day that he died. People think about love and friendship and they laugh at the way that Emporer Claudius thought he could stop love, but love cannot be defeated.
