I could feel I was losing myself to this girl in this bed. He stood up and put a new CD on. “Darling, you send me, I know you send me, honest, you do …” I’m thinking, “What is this?” He crawled back into bed, and tried to mash at this point his third ball into my vagina. On his fourth thrust, he gave up and fell asleep on my breast. His head was heavy and his breath was so sour, I had to turn my head so my eyes didn’t water. But they were watering anyway, because of this song. Who is this? This is so beautiful. I’ve never heard these songs before. They’re gutting me. The score attached to our morning couldn’t have been more off. His sloppy, tentative lovemaking was certainly not in the spirit of William Wallace. And now the most beautiful love songs I’ve ever heard play out as this man-boy laid in my arms, after diminishing me to a last-minute booty call. I listened to the songs and I cried. I was looking down at myself from the ceiling fan. What happened to this girl? How did she get here? I felt the fan on my skin and I went, “Oh, wait! I am this girl! We got to get me out of here!” I became my own fairy godmother. I waited until the last perfect note floated out, and escaped from under him and out the door. I never heard from Matt again, but felt only grateful for being introduced to my new self, a girl who got her value from within her. I’m also grateful to Matt for introducing me to my love Sam Cooke, who I’m still with today.
