Violet was a bitch
We never knew much about Violet. She never had a backstory to her character but apparently she was a bitch. She WAS Lucy's friend I guess and birds of a feather, as they say.
But seriously, what kid sits down and makes TWO party lists. One for those she wants to invite and one specifically for kids she DOESN'T want to invite?
And given she still invited a disease covered person like Pigpen to her party what kind of hygiene would a kid need not to be invited?
