For those unaware, it is generally a bad idea to change things on an autistic person. Autistics shy away from new things. The idea of trying to get Buddy to do new things causes my heart to skip a beat, and I avoid it as much as possible.
It started when he was a baby. I began to notice immediately he did not like going to new places. If I wanted to rearrange furniture, I had to do so where he could see, or he would have a meltdown. Even after he saw me do it, if he left the room and came back, he would be fussy. He would touch everything to be sure they were still there. This made moving very, very difficult.
