While my wife and I were courting online on CC we also exchanged real letters. She used stationary and cards, I like to use little tiny stickers on my letters to convey certain emotions I was feeling about her. Every day I would anxiously await for the mail to be delivered because I knew my honey was writing me. I guess for us our favorite subject was about the life that we were going to share with each other. Wonderful intimate, romantic, playful, serious love letters.
