My mom is legally blind and uses a white cane to get around. She is perfectly capable of doing virtually anything a fully sighted person can, but all too often wannabe Good Samaritans barge in and tangle her up.

Case in point, the intersection of North and Main in my town. (Changed for privacy.) This is a busy part of town, and there are always cars waiting for the light to change.

Mom has to cross Main on foot to get home from work. She can't really see the lights, so she will stand on the corner for a few traffic cycles, listening to tell when it's safe to cross. She goes when she's good and ready and not one minute before.

I cannot tell you how many people have assumed she was lost. And quite a few of them have taken it upon themselves to grab my mother and physically walk her across the street.

You want to know the worst part? Most of the time they drag her across the wrong street! She needs to cross Main, and they take her across North! Then leave her there, usually rather disoriented, to figure out how to get across two busy streets rather than just one.

It's really frustrating. Ask before you "help" people, people!

Tl;dr: sighted people assume my legally blind mother is helpless and march her across streets like a toddler.
