Communicating with Callum

Speech Therapist: Let's talk with your hands!
Callum: (Silently shakes his head no.)
Speech Therapist: Here, let me show you.
Callum: (Gives her The Look.)
Speech Therapist gently takes his hands, Callum takes them back.
Speech Therapist gently takes his hands again, Callum takes them back and shoves them down his crotch.
Speech Therapist: See? He's hiding his hands from me, but I'm going to keep going.
Speech Therapist gently takes his hands, Callum takes them back and makes a big show of sitting on them.
End of session.
