I've been rewatching the Black Moon Arc and something occurred to me. Chibiusa learned the wrong lesson from falling in the rain and her parents refusing to help her up. (Terrible parenting, btw. Yes I realize it was well-intentioned, but backfired horribly.) Why didn't Chibiusa ask Usagi and the others for help? Sure she does eventually after breaking down crying, but it's not her first response. Why not? In addition, the whole trouble began when instead of Chibiusa seeking an adult's help for dealing with bullies she stole the Silver Crystal to prove some sort of point. Is it possible the incident in the rain taught Chibiusa not to trust or seek help when it was needed?
