Dear [recipient's name]:

It's appropriate that the holiday coming up very soon is called Sweetest Day, because to me, you are just the sweetest. I have treasured every moment we've spent together throughout our entire 26-year marriage, sweetie. I really mean that. In good times and bad, our relationship has grown stronger with each year that we share.

Now, let's do something fun to celebrate. I have some surprises up my sleeve and will be telling you soon about the special romantic weekend getaway that I have planned for us. I love you for making not just Sweetest Day but every day special.

Love always,

[Signature]
