The United Spinal Association has a great pamphlet on Disability Etiquette. It’s light, conversational (plenty of comics with situational examples), and friendly in tone.
This goes a long way in increasing awareness about a host of disabilities. It also is a very useful tool in combating the fear that stems from not knowing how to communicate with someone. How many times have you seen a person completely ignore someone else, for no other than they didn’t know how to communicate with them?
I found out about it because today is veterans day. The version I saw, in paper form, was branded with a VA logo instead of the United Spinal brand on the cover. Whatever form you find it in, grab (or order) a few extra copies to send along to friends and colleagues.
