There are no rules to follow; you can be clever, foolish, funny, intimate.
You can whisper sweet nothings, exaggerate as much as you want, even tell little white lies.
If you want to write poetry, now is your chance. If you have no talent, crib some lines from someone else.
There are no laws governing the length of a love letter. Make it as long as you’d like.
Create an intimate nickname for your loved one, but remember, it can come back to haunt you. Charles Dickens wrote to his wife Kate: Dearest darling Pig; Zelda Fitzgerald to F. Scott Fitzgerald: Dear Goofo.
Some of the world’s greatest love letters were written by a Napoleon Bonaparte — a man whose fame came from his military, not his romantic, conquests.
Napoleon to Josephine Beauharnais: [I'm sending you a thousand kisses by letter]…but give me none in return, for they set my blood on fire.
After their marriage, he wrote: I have not spend a day without loving you; I have not spent a night without embracing you; I have not so much as drunk a cup of tea…. In the midst of my duties…my beloved Josephine stans alone in my heart, occupies my mind, fills my thoughts.
Even later, in the middle of a campaign through Italy, he wrote to her, closing his letter with: I hope to hold you in my arms before long, when I shall lavish upon you a million kisses, burning as the equatorial sun.
