In my time, we would send Saint Valentine's Day post cards to friends and family and lovers alike. I remember that my husband was able to send me one from the front lines in France. It made me so happy to receive it, even if we were not more than friends at the time. It is a shame that the post is not utilized more in these times. We had the most beautifully drawn Valentine's post cards. Some of them were very sweet. Others were quite risque.
