dont talk to disabled people as if theyre children or some kind of pet, literally do not do it.
its not cute or considerate, its not the “right way to talk to them” its honestly disgusting and you shouldnt talk to anyone like theyre less than you.
its patronizing and rude, and if youre talking to them like that because theyre disabled, whether it be mentally, physically or chronically, its not only wrong, but incredibly ablest as well.
