I agree, I have absolutely 0 issue with patiently leading people through a process. Even if they're a bit confused or unsure, as long as they are honestly listening and trying, I will try my best to explain things in a way they can understand. The thing that pisses me off is when people go all learned helplessness and try to get you to do it for them instead. No, I want you to try and learn it for yourself. If it doesn't stick, I'll patiently guide you again. Just try. Believe me, people of any age can "get" technology or refuse to learn. It's a mindset

I will make an exception, and that's when I'm dealing with people who literally cannot learn. If you have dementia or a severe learning impairment that's a different story, usually those folks will have someone else who can learn for them though.
