My letter for this week is obvious: a Love Letter for Valentine's Day.
I believe that the requirements for a love letter are simple: Sincerity, Specificity and Schmaltz. Write from your heart. Note specific reasons why this person is special to you. And don't hesitate to get sentimental. It is LOVE letter, after all.
Now maybe you're 'not that guy' or girl:
Don't despair. Just like Carrie Bradshaw's boyfriend, Big, in Sex and the City you can take inspiration from others. Love Letters of Great Men and Women: From the Eighteenth Century to the Present Day, by C H Charles contains excerpts of letter from Beethoven, Mozart and Churchill (!). Of course, not everyone is in a RELATIONSHIP with a sweetheart or spouse so your Love Letter could simply be a letter to someone you love.
Share the Love!
