Laughing Jack hates kids. Sally's a kid. Therefore LJ would hate Sally. if LJ liked kids he wouldn't brutally torture them for fun and why would a little girl want to hang out with someone like that anyway?
{{talk outside of my bubble please}}
{{Think you can explain?}}
"Oh! Of course! Well I don't know where you got the idea that I hate kids. I love kids! Maybe a different me don't like them, but I'm not that me."
{{....you do know killing kids is bad right?}}
"Doesn't make it any less fun."
{{Ooookey. What about Sally?}}
"Oh. She already played that game with her uncle. Also my powers don't work on ghosts, at least not well. Also she is a delight to be with."
{{really? What do you say Sally?}}
"Mr. LJ is great at tea parties and fun to scare people with. Also, he pinky promised that he would not do or show me any of the mean scary stuff."
