Avner would become mute and disconnected from everything else around him. On one occasion, he left the Scout House to sit on a bench outside. When our Scoutmaster, Crill and I tried to speak to him, he refused to acknowledge us. I tried to get him into my car at the end of the meeting. Instead, he got up and started walking towards home, only a mile away. I called Barbara from the Scout House to let her know that Avner was walking home. He walked past her which worried us both, but eventually turned around and came inside.
