Autism Stimming

I walk through the street flapping my hands.
I sit at a bus shelter rocking back and forth.
My arms sway of their own free will.
My legs move around and sway me.
I bounce happily from side to side.
People stop and stare but I don't care.
Why do you look so shocked?
It won't hurt you will it?
You should try it, it's relaxing.
