He summoned a demon from Hell, following instructions from a journal his grandfather wrote on the subject before being the victim of a sort of faust-like debacle himself. A little imp popped in from a cloud of smoke following his ritual. It turned around, and when it saw him it rolled its eyes and said: “Oh, it's you.”
“Yeah it's me,” he said. “How are you?”
“Look, kid.” It said, taking a seat on the magic summoning circle. “You're a great magician. You really are. One day you're going to be very rich and you're going to be happy in a desperate, shallow sort of way if you play your runes right, but you've got to stop calling demons in just to talk.”
“I can summon demons to do whatever I want,” he said.
“Technically, true,” said the imp. “But we're usually reserved for killing people, burning down villages, granting asymmetrical pacts, torture and the like, not talking to lonely children.”
“Why not?”
“Read a fucking fantasy novel kid,” said the imp. “I haven't got all the answers.”
He sat on his bed and said: “Sometimes do you ever want to just run away? You know, from work and stuff, and just disappear.”
“You want me to make you disappear? I can fucking make you disappear.”
“Have you ever fallen in love?”
“Yeah,” said the imp. “Fell in love with a gorgon. Really pretty, beautiful flowing locks of asps.”
“I like this girl. She doesn't know I exist.”
“Then summon a fucking lust demon and you can screw her all you like.”
“No, no,” he said. “I want to have her love me, not just want me. Do you know what I mean?”
“Humans…” the imp said, shaking its head. “You give them bodies and that's not enough for them. There has to be a soul or whatever. Something inside. Some magical inside. Fucking idiots.”
“You think I should write her a poem? A mystical poem?”
“That will trap her soul in a jewel?”
“That will make her fall in love.”
“Yeah, what's the difference…” said the imp. “When you give her a wedding ring, isn't that trapping her soul in a jewel?”
He laughed. “You're funny!”
“Yeah, go fuck yourself.”
“You can go now, demon.”
“Thank god, you lowlife,” and it was as if the imp was never there.
This is wonderful. Those danged demons.
(I think you could lose the last two lines and have a stronger punch at the end.)
