February 14th is Saint Valentine's Day, a traditional holiday in the west. Saint Valentine's Day began in Europe and has been celebrated for hundreds of years. It is not a holiday from work. No one gets a day off. On Valentine's Day people usually send romantic cards to someone they love or want to be loved by. The cards are called "valentines". They are very colourful, often decorated with hearts, flowers or birds, and have humorous or sentimental verses printed inside. The basic message of the verse is always "Be My Valentine", "Be My Sweet Heart" or "Lover". A valentine is anonymous, or sometimes signed "Guess who". The person receiving it has to guess who sent it. This can lead to interesting speculation. And that's half the fun of valentines.
