My son is very sensitive to tone of voice & body language.
Just yesterday, I had something on my mind when we were driving to the lab for blood work. He kept asking me what was wrong, so I finally asked him why he kept asking me. He said it was because I was responding the same way I normally did. So, tone of voice & body language was OK, but pattern of speech wasn’t.
Sometimes, he’ll just look at me and know when I’m bothered - it’s kind of surprising.
The funny part? He keeps asking me if he’s autistic. If anything, he’s the polar opposite of autistic - he picks up on human emotion too well.
