Caring equals listening to them from the first to the last word, but agreeing to their thoughts means adopting what they have said as your own, be it partially or completely.
It should be inherently harder to make someone care, rather than agree, as we all have gaps in our ideals and knowledge that others often fill up, but finding people worthy of doing it is proportional to your own intelligence and even personality, to a degree.
Fuck phone typing, it takes ages to type even a portion of what I want to say.
