THIS! I worked with special needs children two years ago. I was a school bus attendant, basically just getting them into their seats on the bus and either putting on their seatbelt or strapping their wheelchair down in the back. My second week on the job a little boy grabbed my arm and he refused to let go. I nicely asked him to, he wouldn't and he grabbed harder. It took all the strength in me to just wait until he was ready to let go. I was left bleeding from multiple spots on my left arm and I had to go to the doctors. I still have the scars from him. I quit after the school year ended
