Staying with it a bit longer, I wonder if you agree with a site bringing on examples of causatives:
“Have (give sb the responsibility to do sth) —I had John fix the car. I had my hair cut.
Get (convince or trick sb into doing sth)–He got the mechanic to repair the machine. She got him to read more.”
Do you really distinguish them that way? I mean ‘convincing\tricking the mechanic into repairing’?
