I've never had any problems with the "mother/mothers-in-laws" in my life, it was always the men
but women get such a bad press imo., where are the father in law jokes, I'd like to know!
I think I had a wonderful mother. I thought my first mother in law was a very nice kind woman, we got on although she only spoke French and mine isn't great, we still managed to communicate. My second mother in law, was also really nice I think she had a lot of time for me because she said I was the only one in the family who bothered really listening to her.
On the other hand I had difficult relationship with my father. I didn't really like either of my 2 father in laws, both were really opinionated in their own way. Ex father in law rubbished the English pretty much most of the time, who in his words were "double faced" no generalisations there
worst of all he droned on and on about English food, apropos of living in London for a while in the 1950s and hadn't been back since. Post war was a drab time anyway for everything. He always took delight in reliably informing both me and his son "The English boil everything even the meat" cuisine like everything else had moved on a lot by the late 1970s but he was forever mentally stuck in a Brown Windsor Soup time warp. My ex even told him to "shut up" occasionally, with a "you don't know what you are talking about" Then blow me down when I married again, I got the reverse from English father in law disparaging the French, who he hated with a passion, in spite of never taking his stupid self there, or anywhere else for that matter apart from Ireland and Scotland. He also came out with all manner of rubbish such as when he and my husband were playing golf down on the south coast allegedly he'd look across the channel and say "civilization ends here" to which my husband retorted, "no it's starts over there and you're talking rubbish as usual" when our children were young we took them to France all the time, which seemed to annoy him. I also have family there. I'm glad he and my father never met, my father was quite ill by then. They would have had absolutely nothing in common. We went off and got married quietly and told both sets of parents afterwards, just as well because my very catholic father couldn't get his head round his daughter getting a divorce
my mother was a bit sad about that, but was far more accepting and a later stage told me although she liked both my husbands, admitted to really, really liking my 2nd, more than my first which pleased me as I regarded her as a good judge of character.
