Dear Imogen,
I'm surprised you haven't found out who I am yet. I'm usually the nervous type, but I try not to be so I won't reveal myself to you early. I guess I'm glad you haven't found out who I am after all.
"At the touch of love everyone becomes a poet." -Plato. (Am I a poet yet?)
My dearest love,
Your secret admirer.
P.S.: The way your hair flows down your shoulders really compliments you.
