"Yo. 'Sup, shithead."

Carrie walked into your quarters, wearing camo pants and sleeves, her hand formed up in a rock-n-roll sign as she stuck her tongue out.

Despite her tough and rude approach, she was actually your closest friend in the military. Wherever you were, she was there to follow. No matter what position, rank, or mission, she was there till' the end. Like an unwashable smudge. A smudge that you cared about and befriended.
