He Is Not a Fan of Balloons

One of the things the ABA therapists will do with Zack is to use a pump to blow up a balloon, and then let it go so it flies around the room, making that incredibly loud screeching noise.

Zack doesn't like it.  The other day his therapist got the balloon pump out was digging through the bin for the balloons when he realized Zack had left the room.  He got up to look for him and found him standing in the corner of the shower.

"No pump."  Zack looked up and told him.

He's a little man of few words, but he gets his message across.
