(my eldest son has Asperger's...and this is a little story about him and his tendency to obsess over a subject matter)
" ...so far he had found 17 different license plates.
...he said it was a new plate he hadn't seen before
...his fixation caused a lack of thinking as he hurried across the street without looking
...luckily I was there to pull him aside
...he was right. It was a new license plate.
...and I was frazzled!
