It only takes a little time to educate children about disabilities. My son is autistic and if parents would only talk to their children about others and their differences I wouldn't have to explain to much to my own child about others lack of knowledge. If that sounds mean it's not intended to. My son gets his feelings hurt and doesn't quite understand why people are so rude to him. Honestly these people just don't know all about autism and that's why we have to advocate and educate.
