Observations!
Crankies like normals because of their kindness and patience. Both have insecurities about making friends, so I guess together they make what they lack!
Peppies and snooties understand each other to an extent, with peppies doing more of the talking.
Crankies and snooties get into love-hate, where it's more...spicy than sweet? Haha weird wording but they fight and make up sort of thing. This happens between snooties and smugs too, except I notice they are a lot less forgiving of the smugs and fight a lot more.
Normals are a little naive so unlike snooties, they have little crushes on the smugs. They'll always comment on how nice and gentlemanly they are and never notice their egotistical or manipulative side.
Uchis and lazies have a brother-sister relationship! They fight over little things but really enjoy each other. I've seen Cube get scared when he had a summons from Phoebe because he thinks she's scary when she's mad, haha.
Snooties are motherly at times to lazies, and at times depend on lazies for a break from being...snooty, or what I assume is "the adult world".
Uchis and snooties duke it out hard. Uchis probably cannot stand the cynical and genuinely mean parts of snooties.
Crankies think lazies are childish and will often hurt their feelings by commenting on it. They also are offput by peppies...peppyness.
I like these sorts of things 8'D.
Oh and, I'm unsure if this is because of how much they talk about themselves, but I noticed peppies tend to be the loneliest? I mean normals are the ones talking about wanting friends and such but in the end they always find one. Maybe it's just me, but it makes me think about them in a very different light sometimes.
