your parents went out of town with your sibling and left you behind (sorry if you're an only child) but they didn't realize that they left you behind until they got to their destination, so they hired Lucifer to babysit you

he sat on the couch with you as you both watched a movie in silence, his jacket was hung up as well as his hat

"So... Your parents told me nothing about you, can you tell me a bit about you?"
