I also wanted to say that having met Thomas T (Dilli) my respect for him has grown tenfold in regards the way he deals with his sight issues and his very healthy attitude in dealing with it..
I'd also like to say that having insisted someone isn't able to work because of a disability then it's not particularly helpful of government/social services to not help provide you with the wherewithal to AFFORD those items that make you at least an active and as independent member of society as you can be by insisting you purchase items at cost when the benefit only covers your day to day living.
