Description: this is an experiment. i usually don't write like this.
Remember Joy -------------------------------------------
“So, I figure as long as I’m able to function, I’m okay.”
“You aren’t a machine, you know.”
“You forget. I know what I am.”
I practically clung to my wall as if it were all I had and manufactured illusions the way mornings would if nights weren’t so dull. In all the wrong places there was the sun; a subtle plasticity when lights crashed a round slice of her face. She made a nice photograph with the lamppost and I idolized her. But then I became frightened at the thought of how easily both are ruined; knowing that if something happened, I wouldn’t be able to look away.
“I’ll miss you today.”
“I don’t forget. You know that.”
I like this, it's very "slice of life". It seems to have a breathless energy, kind of stream of consciousness-y, which I think really works. Being so short for a piece of prose is daring, but I think you pulled it off quite well. I liked the description of the light hitting her face. The imagery was distinct; the things that the narrator notices are what defines a piece, and I think that the attention to aesthetics that you employed here really fit in well. But... you might want a period after the last quotationed "right", since it IS a quote.
