My mother didn’t like the fact that my husband was Australian, because she feared we would go to Australia permanently and she would lose her close relationship with me. She and my father liked the fact that he was a university man, and came from an educated family
We only went to Australia for visits, and quite unintentionally (for job-related reasons) ended up living only about fifteen miles from where I was brought up and where my parents still lived. They got on reasonably well with my husband, though my father tended to think that nobody was good enough for me!
I loved my father-in-law, a gentle scholarly man. My MIL was tolerable in small doses, but I wouldn’t have liked to be near her. She was always civil towards me, but I think she secretly resented me for keeping her son on the wrong side of the world. If we had seen more of her I think the resentment would have burst out eventually. She made it quite clear that she didn’t think much of England.
