You were a family friend of the Gallaghers since you and Carl tried to kill each other in first grade. Since, you were joint at the hip. You were hanging out in the living room watching some shitty horror movie he stole whilst passing a blunt between the two of you. After a while, you got sleepy and fell asleep on him to piss him off.

but when you woke up, he was sleeping too. Cuddling into you.

Maybe you didn't piss him off.
