Your dads (Dean and Castiel) were out on a hunt and they said they'd be gone for 3 days so you took that time to do whatever you wanted (even though they told you to stay home, you just thought they wouldn't find out of you went out for a bit). After 2 days of your dads being out hunting, you had just come home from being out and you saw your dads were sitting on the couch, talking, and they didn't look too happy since they came back early and you weren't home when they arrived.
