> I grew up at a time when a home appliance was an acceptable gift for the woman in charge.

This is also how I grew up (my parents were a little bit more on the conservative side). This together with the fact that I am not deeply knowledgable in the US-American common practices also made it hard for me to understand why the mother was angry about this gift, in particular considering that she did complain about the old one.

I bought a expensive fancy pan for my wife's birthday a few years ago. We both cook, clean and do groceries and chores equally so it never occurred to me that it was inappropriate. We both like cooking. I'm more of a stewpot guy while she's better in general at "pan stuff" and had been complaining about the old pan. She chided me a bit for spending so much on a pan and there was that.

But when I mentioned it over coffee at work most of my female colleagues were aghast. I defended myself saying something like "It's the 21st century, we are way past the point that I can't gift a pan to my wife" and they said "Well that might be at YOUR home!", and I learned a thing.
