if you tell somebody you're going to to do something, you're not asking them to take responsibility. you're telling them that you're taking responsibility for whatever you're going to do. If you ask somebody's permission, you're asking them to take some portion of responsibility for what you're doing.
which is the same risk that the sibling comment is warning about - if you're trying to do this for things that you aren't ultimately responsible for, you're goign to piss people off. only take responsibility for things that are actually within your area of responsibility.
