Kathy's Self-Portrait: The Making Of

On the night Kathy filmed her self-portrait, she had the help of Melissa, Harmony, and Spidey. Not wanting to lose the memory of this event, Melissa decided to jot down the many things said then. Later on, we realize that, without proper explanation, many things could be easily taken out of context. So here it is, completely explanation-free.
 

"Mine's not very big."
"Mine's even tinier."
"Are we gonna' do this on the floor? With the lights on?"
"Let's just do it here."
"Spidey's way bigger than this. I mean, tinier."
"Grab him from the front."
"He keeps moving!"
"Aww, I have to be covered?"
"Okay. Let's put my hand in the back."
"I can't force him!"
"How do I make him go backward?"
"He just won't do what you want."
"He's not listening to my commands!"
"But I wanna' see all of him!"
"People can't see what you're doing if you're under that sheet."
"But I can't see him! How am I supposed to do this if I can't see him?"
"Okay. Put me into position."
"This smells."
"Let me see what it looks like if I put my hands like this."
"Where are his legs?"
"Why are you adjusting?"
"LOOK AT SPIDEY GO!"
"No, point it towards here."
"If that gets on your skirt..."
"I'll hold Spidey while you do that."
"It's too awkward now. We never laugh when we actually do it."
"Ah! You broke it!"
"Why do we have so many?"
"Four minutes? That took four fucking minutes?"
"Who screamed?"
"Let's watch it."
