Love, Friday

This week I only wish I had a letter penned by my mother or my father.
I wish I had one. I don't-but I know their secrets.
Long ago I would sneak lookies at cards they left for each other on the wooden kitchen table.
At the bottom of the card, under a signature was always ILYTM in tiny capitals.
On his cards. On her cards.
I found out later, when I had the courage to ask, that it meant:
I Love You The Most
What little love letter quirks do you do?
