Answer:
Since blind people have problems with sight, I can give them some guidance when encountering direction situations or such stuffs that have to do with vision. I can also accompany them and comfort them about they're situation, show them the positive side of life, on top of that, I can also give them a few remarks about some sceneries and world landscapes if they're okay with it.
Explanation:
You can copy or just write what YOU would do if you encounter such situation, not sure about the light thing tho but I guess it's the sight thing.
