People with autism tend to take everything literally, which can make for difficult times. You have to explain every Idiom. But it can also make for humorous moments...
Jonathan comes to me:
"Mom...I'm soooooooooooo hungry. Can I have a snack?"
(It was 4:45, and if he had a snack at that point, he would never eat dinner.)
So, I said "No, honey, dinner is right around the corner"
He immediately grabbed my hand and replied, "Well come on then. Let's take a walk around the corner!!"
Gotta love it!
