Okay, this is going to be a long post, but I'm hoping this set of anecdotes will be helpful to you. Like has been already said above, everyone's different and this is just my own set of experiences with my friends. Also, just to echo:
And for the love of all that's holy, don't make the blind person a superhuman.
On the flip side, do not attempt to blindfold yourself and navigate your house to get an idea of how a blind person would do it. You've used sight your whole life, so of course, it will be disorienting to you and you won't be terribly good at it. Someone who's grown up without it has already adjusted and is much more skilled than you are.
My best friend is legally blind, though can read regular print if the font is big enough and she can bring it close to her face. I took notes for her throughout school on this cool note-taker that made a copy of everything I wrote. My notes were always filled with little doodles and in-jokes.
One thing about school was kids often came up to me asking questions about her. "Can your friend see?" "How much can she see?" I don't remember any kids being mean to her, they just really wanted to know and somehow thought the tactful solution was to ask me. Though they weren't always as fully out of her earshot as they seemed to think. Now, I know I asked my friend some dumb questions myself. She took everything in stride and told me when we were older, "It's okay, you were curious." Even now, when my toddler just got glasses (his great-grandmother sees better than him), I get asked the same silly questions, "Well, how does everything look to him? Is it fuzzy?" (How would I know? For that matter, until he got the glasses and had something to compare it to, how would
he know?)
An amusing story -- one time, my best friend and I went to Disney World together. We told the staff member at the start of a show that she couldn't see and we needed a seat up front. The staff member was very nice and seated us (we cut the line almost completely!) and then brought out the closed captioning screen for her. We didn't want to hurt her feelings, but we kept laughing about it.
While her hearing obviously isn't superhuman, it's definitely more keen than mine. She's heard conversations that I've missed completely. When we were walking down a poorly-lit hallway, I warned her were were close to the door, and she said, "I know that." She explained her voice sounds different to her when there's something getting close to her face.
I had two friends in my Christian club at college who were fully blind. One had been blind since birth. He walked with a cane confidently, about the same speed I would walk. There was one crosswalk in particular at our college that people were notorious for speeding through and often made me nervous. He'd go right through it with the attitude that hey, he's got the cane and he's in the crosswalk and they better dang well stop. (By the way, if you've never seen a cane up close, they do break into sections like a tent pole and can be easily tucked into a backpack or something when you're not using them.)
When he graduated, he made a point of going out to breakfast or lunch with each member of the club before he left. I remember him talking about how in other countries, he might be cast aside or isolated and he was really grateful for the opportunities he had.
Now, my other friend from club had only been blind a few years. She didn't walk nearly as fast. However, she had a great sense of direction. I was driving her home at one point and didn't know the area. I got lost at least three times. Every time, she asked me, "Okay, tell me what street/landmarks you're near." I'd tell her, and she'd direct me back to the correct route.
Usually blindness doesn't come up in our conversations that often except to remind someone of an accommodation needed or just to vent about someone being clueless: "Um,
hello? Can't see!"
There's a funny scene in Avatar: The Last Airbender where someone holds up a flyer up to a blind character and demands, "What's this?!"
Her reply: "Well, it
sounds like a piece of paper, but I assume you're referring to what's
on the piece of paper."
People do make mistakes like this in real life, sometimes even when they know the person. It took me a while to gauge how big/up close something had to be before my best friend could reasonably read it.
Like I said, I know all this is long, and I know I can't personally describe how any of my friends felt during any of these scenarios, but I hope it's helpful nonetheless.
