Make an effort to include others even if you are not sure how.
Never exclude a person simply because they look, act or speak differently.
Show with your actions that you want that person to part of your activity (ie., classroom, sporting event, trip to the movies, lunch table). Invite and encourage them to join you. In other words "walk the walk, not just talk the talk.'
Take the time to get to know someone even when it takes you out of your comfort zone.
Don't ignore someone because they don't seen to fit in. Ignoring is a close kin to bullying.
Make the effort to figure out how to make that person feel more accepted. Do they need a quieter place, or maybe a personal escort into an unfamiliar situation?
Be an example-setter by always treating others with dignity and respect.
Be a helper, volunteer or community participant at activities that include individuals of various abilities.
Learn sign language so that you can communicate with all types of people.
