Sandy Could Be Very Disruptive in Her First-Grade Class

Sandy could be very disruptive in her first-grade class. She sometimes would scream and use foul language when she was frustrated; she mostly kept her hands to her side while interacting with her friends in the playground; and she would stare right into the eyes of her teacher when he was explaining lessons. Her teacher, at his wit's end, complained to the principal that Sandy was autistic. Do you agree or disagree with the teacher? Explain your answer.
