She was raised in occupied territory during WWII. I do think she means well, but it’s a combination of deprivation mentality and being “peasant shaped” with a husband who wanted big boobs and everything else basically child sized. He was a string bean himself. So she (and I) spent the years from 1970 on on a diet of some sort, right at the same time the US went off the rails with the religion of low fat eating.
And I will say she’s better about this if I bring food and we eat in her apartment, but most of our meals are taken in the community dining room, where the Most Important Thing is that I behave in the way that she thinks will impress her friends. I frankly hate these visits but she’s getting too old to handle much else
