be (one's) place (to do something)
To be something that one has the authority to do. Often used in the negative to mean the opposite. I know you're just trying to help, mom, but it's not your place to discipline my kids. As much as I want to tell my neighbors what to do with their Christmas decorations, I know it's not my place to.
