I’ve never heard of pink/blue chores before!
I am the gardener, snow remover, and household fixer in our family. H does the bills because he has a complicated spreadsheet that he likes to keep but I’m perfectly capable of doing them if necessary.
The only thing that I make H do that could be considered a “blue” chore is kill bugs. I have an irrational fear of creepy crawlies. Tried very hard to not pass that down to my D and even held a tarantula when she was 8 years old to “prove” I wasn’t afraid. (Still gives me the heebie jeebies thinking about it.)
Thankfully I never got the message about “pink careers” either. I was always strong in math and science. Never a question that I would go to college and do what I wanted.
I’m thinking that maybe even a 10 year age gap makes a difference in that experience. I graduated from college in the early 90s.
