Thanks for the link!
The letter below really nailed it for me. The "You and Laura Are the Greatest!" along the bottom-left margin is a bit too "kissing up" for my style. And underscoring the word "greatest" is too sappy. If you want to communicate that "You and Laura Are the Greatest," put it in the actual letter; don't handwrite such a compliment off to the side.
