I'm sure you're not an idiot. Though I was critical of your question, I'm sorry you were called names in this thread.

I apologize. Many times people come here and ask questions that infantilise blind people, such as how do you wipe your butt, how do you feed yourself if you can't see, etc. I had a woman on a bus once get excited because I put my hair up in a pony tail and she had "never seen a blind person do their hair before!" People also come to this sub and type jibberish once they learn about screen readers.

This had led to me being defensive and I do apologize to you. Your question was asked out of genuine curiosity.

I'm not implying that it would be hard for blind people or that they can't be done or done well. When I posted this question, I genuinely didn't know the answer and I came up with some scenarios that didn't seem plausible and I thought hmmm, I'll ask people who are the experts in answering the question. As I told you in my last comment, I didn't want to make assumptions. The answer to you may seem blatantly obvious (you've told me more than once now I should have been able to easily figure it out myself) but guess what - it wasn't obvious to me, which is why I asked.

As someone who has medical issues, I do know how creative and resilient people can get with finding alternate ways to do things and I don't doubt at all the abilities and independence of people who are blind.

I did actually did try googling how blind people perform this action but couldn't find an answer and anyway, people may have come up with different solutions to one another. Although I do admit my research skills aren't very good in comparison to some other people's so maybe the answer is out there somewhere.

But seriously, heaps of stuff on reddit could theoretically be found on google somewhere, but the whole point of reddit is to share and discuss stuff with each other, not to only discuss stuff that couldn't be found otherwise on google. It is a social network. That's probably one of the reasons people post stuff on here that could be found elsewhere.

Keep those negative assumptions about me coming, though... I'm clearly some sort of stupid, idle person who belittles the abilities of people who are blind.
