Sorry OP, but that doesn't sound right or normal
It's pretty normal in my circle, OP. I suppose most of my friends are SAHM and so they have traditionally had a bit more time to do that sort of thing in, as did I before I went back to work.
I can't speak for them, but for me, if I had time to do something useful while my DH was working, then I'd do it. Now I'm working again, we share it, although it's a hangover from me doing most of the card-writing that I do a few more, as I used to chat with the neighbours, milkman, postman etc. so although technically a 'family' thing, I actually made more connections than my DH in a domestic sense.
He's always done his family ones though.
FWIW, we have a very even split of stuff we do to keep the show on the road, and DH probably does a bit more than I do. Happy, balanced family life is made up of thousands of tiny kindnesses and a willingness to help each other. Isn't it a bit dismissive of someone doing something happily and willingly to refer to it as 'wifework'?
When my DH says "what are we getting for [his nephews]?" I just shrug
Not my circus. Not my monkeys
Are they your nephews as well, though?
