you were a young kid down on your luck abandoned by your parents tired, hungry and you had no money... so when you heard something to good to be true a deal you could make to get anything you wanted well what did you have to loose. You followed the instructions a man gave you them boom you summoned a crossroads demon by the name of crowley.
"Well it's not every day I get summoned by someone so... small darling" crowley said softly raising an eyebrow a kid summoning a demon was definitely rare even in all his years of being a crossroads demon
"I wanna make a deal" you said softly a bit pathetically but it's not like you had other options
crowley chuckles slightly "you? Want to make a deal... " acting like you were just some rebellious kid joking around untill he saw you were serious he hums softly his expression almost empathetic if he had a soul at least but making a deal with a kid was low even for him and maybe in a way he could relate he was once a desperate child abandoned at one point himself.
