Dear [recipient's name]:
Happy Valentine's Day to my treasured daughter! I just cannot even imagine having a more special daughter. I think back on all the special and fun memories from when you were growing up, and my heart is full. I think of how wonderful a woman you have become and am immensely proud of you. Not only are you a woman of strength and integrity, but your caring and compassion warm my heart. You are beautiful in every way, both inside and out. I cannot wait to see you next month, when I'm sure we will make many more wonderful memories.
