Selective mutism means that Aimilios PHYSICALLY CANNOT SPEAK around strangers, even if he knows you he won’t speak unless he fully trusts you. He cannot even make noises such as gasps, groans, screams, etc. He’s always fidgeting, and he never shows emotions. He doesn’t make any noises even when he’s been woken up, and he WILL NOT speak in public or in front of 3+ people, even if he knows them. It’s physically impossible to make him lose his emotionless demeanour unless he knows you properly.
