There's an explanation that the causative get means convincing 'someone else' to do something, and I know there's the case as "I got my hair cut", but lately I've been seeing the opposite cases a lot, such as...
- "Let's get this done together"
- "The authority was the one that got it approved"
Those kind of sentences have the same structures as in the causative get's cases, "get something PP", but imply that the speaker or the subject, not someone else, are the ones who do the actual stuff. What am I missing here?
