mute

>Firkle is somewhat mute. He only talks to his family and friends. He's only mute in public such as school, restaurants, or just around people that he doesn't really know. Firkle is a demisexual demiboy, he is only out to his friends, he thinks he will never really be ready to come out to his mom since they don't talk about the lgbt+ community along with politics.

>Ike is a somewhat popular boy. most of the girls like him and a few boys to. Ike plays hockey, and soccer. people like to call him a jock but he doesn't like to see him self as one. Ike is openly out as pansexual, he doesn't care about one's gender but he does care for peoples personality's.

hello!! and yes what is has is a real thing. It is called selective mutism, it is an anxiety disorder where you are not able to talk in certain social situations. The first part of the book will be going over certain things such as stereotypes that are placed on the two boys.
I also do not own South Park, that credit belongs to Matt Stone and Tray Parker. I hope y'all enjoy this book and hopefully many other stories to come in the future.
