Hi!
My problem is my soon to be daughter in law - she calls all of the time to chat. I am currently working a number of jobs part time while starting my own business and raising a 10 year old daughter. While I want to foster a good relationship with my son's future wife, I have stuff to do that can't be done while on the phone. If I tell her I am busy she just calls back later - she doesn't get that I am always busy and when I am not, I have things I want to do besides talk on the phone about her life. She is 22 as is my son. When my son calls we talk about events, books, movies, philosophy, etc. and not about his day and what his

have said and done.
I admit now that she is working the phone calls have diminished, but I am dreading the time when they have children and she starts quits work to stay home because she will be calling daily again.
How do you politely tell someone not to call so often without hurting the relationship?
