Dear Mr. O'Brien,

You're my hero. I can't think of a better word because you are my 

Teacher

Director

Father-figure

And of course, a family friend of sorts. 

It's complicated. When you rest your hand on my shoulder, I am comforted by your strong presence. I believe that you will protect me. I know that you love me. You carry my burdens on your back, and I carry your memory in my heart. I never have to impress you. 

I love you. I will remember the shape of your nose and the color of your eyes and the stubble on your chin. 

Goodnight.
