Why is it that with some people, they always have to voice their opinion or try to pretend like they have to?

correct you for perceived moral shortcomings that you have? It's like, you don't know them all that well, but they have to make concluding inferences on your behavior and then have to say, "you have to fix this, you have to fix that. You're bad at this" .I've never met other people like this before. My other closer friends just accept me the way I am and we're friendly acquaintance with eachother. But these people are opinionated and patronizing that it's unbelievable.
