My sons father rings a couple of times a week to speak to his sons. If i pick up the phone he just says hello, no how are you or who it is. This is really trivial i know but it bugs me. Sure we are divorced but i did spend 17 years of my life with him. Should i ring and tell him not to call & to call the boys on their mobiles or is it better just to ignore this. I know this is a trivial little thing but it is bugging me . I just feel so irrelivant.
