years ago I had tattooed a few different developmentally challenged people, and at first its a little different and odd,but after your done they always seemed more happy and satisfied than your usual customer. Tattoo's can and do bond us together in many different ways. these "special needs" people need to feel special and ok , just like everyone. I have also tattooed a few physically challenged people ,who have passed a long time ago , they to deserved that same respect, to feel special and ok.
