-We can't exactly lie about who we are. What's the chances that someone who is disabled is a Secret Service agent or Kung Fu Master?? What you see is what you get when it comes to people like us.
-You can tell we have experienced a lot of pain in our lives. We have all gone through some really crazy stuff in our lives... more than the average person. Going through that stuff makes us more sensitive about certain things.
-Disabled people are some of the most motivated people you will ever meet. We are in a disadvantageous situation as it is and the need to be considered an equal in nearly all aspects of our lives drives us in all that we do... and we will stop at nothing to achieve that sense of equality.
-We cherish life in a way that no AB can.
That's all I can think of at the moment. Feel free to add in any additional benefits :)
