Re: This is gonna suck.
did... you seriously just tell a blind person that you're "sure" they can "find someone" to just be a screen reader?
if you *really* do sympathise with the difficulties that come with being disabled, then please, heed my advice: comments like the one you just left aren't helpful, and in fact, they are patently unhelpful.
this person quite obviously knows their living situation and everything associated with it. if there was someone who lived locally enough that would help, that the person trusted, that they would do that? instead, they said their *only* option would be taking it to a store, which they didn't trust with their computer.
which goes to say that if there were a generic Someone they could ask "to be a screen reader", they probably wouldn't trust that they were only doing what was asked of them too.
let alone, like... i'm guessing since you post on this site you've had the "joy" of doing tech support for uninitiated family members over the phone? ones who describe what's on screen in such a bizarre way that you have *no* idea what's going on? that's almost certainly what it would be like for this person with a generic Someone, even if such a person were available.
now, i'm going to assume good faith here, and bring up that: a lot of disabled people (or people with disabilities, depending on what the OP to this chain prefers [people do often prefer one or the other, i usually go with "disabled" for myself rather than "person with disabilities"]) do live independently enough that family and friends don't live anywhere near close enough to just come round and offer support like this on a whim.
i bring this up because it's still very prevalent in our popular culture the idea that disabled people always have family, or a romantic partner, or some kind of hired carer, available at all times. which is simply not the case for a lot of people (even though there are people who need such 24/7 help) and as such, is generally pretty patronising to say something like what you said, that you're "sure [they] could find someone". why? *what* makes you sure? please take some time to think about that.
disclaimer: i am sighted, but disabled in other ways. i do not presume to have all the answers of how to speak to blind/Blind people specifically. rather, i am just painfully aware of how people with all kinds of disabilities get given "advice" like "get a friend or neighbour to help you with it", as if it should be normal for someone to just need the charity of an abled person to do something everyone else can do independently.
