I do not have the habit to call my mil mum or fil Father.. cos I am not staying with them .. and have bad impression with them. Not in good terms too. So when I didn't called them Mother or Father, my hub say I got no manner. What can I do?

One trick I found is not to call the same thing u call ur own parents. For example if u call ur mother "mum" u could call "ma" or "mother". This works if the relationship is relatively neutral but you don't feel that close to them. If u are unhappy .. then maybe harder
