Don't assume anything. It is easy to make the mistake of underestimating a person's potential because of her labels or because she has failed to acquire certain skills. This is a tragic mistake. Always remember that people are people first. Never speak about the person as if he were not in the room.
Relationships make all the difference.
Loneliness is the most significant disability of our time. Many people with disabilities, young and old, live lives of extraordinary isolation. Some depend entirely upon their families for support. A brother or sister or mom or dad are the only source of company. Friends are often absent altogether.
