That is really hard to say, OP, and you will likely know it best yourself given you probably know this person the best. It also depends on what questions are actually being asked.

I myself have some light perception, which gives me a bit of a leg up because I can perceive SOMETHING from my eyes, just no color, shape, depth or anything of that nature. For someone who is 100% fully blind that would be trickier given their eyes literally don't do anything that they can perceive.

I don't understand it at all. It feels like some strange thing that just sounds really weird. Like I couldn't describe it or anything about it, it just sounds so out there.

Seeing is feeling everything around you with your eyes, except there is no physical sensation. Colors are like an extra texture that again can't be felt.

Some object are strange. They don't block what your eyes feel so you can see through them. Or they copy the feel of what's in front of them like a mirror. Imagine a ball that isn't there but everything in your brain is telling you there's a ball in front of you, and everyone else can feel the fake ball too, that's a mirror.

There are still things about seeing that confuse me, being born blind. And even if I understand them in a technical sense, knowing how they work really is hard. I think the things I'd have liked to know as a child would have included:
* That people can see me potentially long before I can hear them.
* People can also see me despite there being potentially thick, sound-deadening glass in the way.
* Frosted glass may not be frosted all the way down.
* People can see at angles you might not expect, including reflections.
* windows can be placed high up, low down, or anywhere in between.
* Lights are useful in social situations.
* society tends to use their heads and faces as a directional tool - I had to learn not to let my head flop down on my chest at a young age. I could hear just as well walking like that.
