I have just interrupted dh while he is talking to his mum on the phone - to inform him I am having a bath. I think he needs to know as any child related stuff will be his duty for the next one and half hour. He has been on the phone for 30-40 mins and his parents are close by (we saw them yesterday) he speaks to his parents on the phone 3 or 4 times a week.
So I am miffed that on the occasional time I interrupt a call to tell him something or by accident. Dh is all frowny face 'sorry mum bigmouthstrikesagain is just interrupting me ...' and acting like he is on a call to negotiate a hostage crisis. I get that it is rude but occasionally interruption are necessary. I have 3 children who follow me round the house asking for biscuits when I call my mum. She lives 100's of miles away and I see her infrequently. Dh would talk to me on that call if he felt he needed too. So grrrrr
