Remember that people with disabilities are people first.
Explore your mutual interests in a friendly way. The person has many interests besides those concerned with the disability. Talk about the disability only if it comes up naturally.
Offer assistance if asked, or if the need seems obvious, but don't overdo it or insist on it. Respect the person's right to indicate the kind of help needed.
Remember that difficulties the person may face can stem more from society's attitudes and barriers than from the disability itself.
Be considerate of the extra time it might take for the person with a disability to get things said or done. Let the person set the pace in walking or talking.
Speak directly to a person who has a disability. Don't consider a companion to be a conversational go-between.
Never start to push a wheelchair without asking the occupant if you may do so.
Don't lean on a person's wheelchair when talking or in other settings.
Don't remove a wheelchair or assistive device out of reach of the person using them.
When pushing a person in a wheelchair up or down steps, ramps, curbs or other obstructions, ask the person how he or she wants you to proceed.
Give whole, unhurried attention to the person who has difficulty speaking. Don't talk for the person, but give help when needed.
Be alert to environmental barriers in places you may want to enter with a person who has a disability. In addition to parking, ramps, accessible restrooms and maneuvering space for wheelchairs, consider lighting adequacy for sign language interpreting and absence of head-height obstacles for people who are blind.
