Who Can Work With The Disabled Students

I can't believe it. Apparently David Edelstein is considering- seriously considering changing his major to Disability Studies. Why? Honestly, I don't see him working with people who have special needs. To me, that just doesn't seem to fit his crazy personality. Who'd actually believe that David would be good at working with disabled people?
This is something, according to Zach, that David has been considering- and talking about- for quite some time. I'm just now hearing about it. How well would David actually do working with people who might have learning and physical challenges- especially if I'm the first person with a disability that he's probably seen?
