My quandary is when is it a boundary and when is it a telling off?
great lesson I learned here - If something is bothering you then it is your responsibility to bring it up.
Boundary is just stating what behavior is unacceptable to you. Until you make your position known then how could someone else know it. This helps avoid the frustration (telling off) and clarify things.
Cheers
