Ohhhhhh her thinking all boys are perverts makes a ton of sense now....Her mom was pregnant at 12 or something.Feel free to r/woosh me but I just realized it.
so this confirms her mom was either violated or had her first time with someone she quickly realized didn't actually care for her and only wanted her body.
Pretty sure it's about sex, not cannibalism. But Carol might have not understood it until she was older.
Or she might not realize it to this day. This does seem the kind of metaphor that would fly over her head.
