Dear [recipient's name]:

Happy Valentine's Day, to a very special friend! Valentine's Day is not just a day for romance, right? To me, it's a day when we express how much we appreciate all the special people in our lives. I want you to know how grateful I am for all the times we've shared--taking classes, talking, hiking, supporting each other, and so much more. I've always known I could count on you, and that is something very rare, so thank you. I know we have so many more fun times in store, and I cannot wait!

Love and hugs,

[Signature]
