FYI: I’ve got RP, with some very narrow, but still decent, central vision. But I need a white cane to get around safely. I’ve got two questions about people trying to help me get around. I live in the US:

Question one: when someone offers to guide me, I know the normal procedure is to grab one of their elbows. But I really prefer to put my hand on their shoulder, so I usually ask if that’s OK. Is there any advantage to me to using the elbow instead?

Question two: I’ve had several experiences when people don’t offer to help, but just grab me and push or pull. Not sure how to react, since they’re really just trying to help, but I don’t understand why anyone would do that without asking if it’s ok with me first
