Socializing with individuals with disabilities should be no different from any other socialization. However, if you’re not familiar with a given disability, you might fear either saying something offensive or doing the wrong thing. A good acronym to help you communicate effectively is: A.D.D. U.S.!
A-ask questions, allow answers.
D-don’t assume help is needed, ask if help is needed.
U-use clear, simplified language and try speaking slower, not louder.
