Also, don't be disappointed if boys just want to be fathers. It's one of the most important and noble jobs there is. Don't discourage it because you don't think it's as important as what you do.
To the GP, if it's OK for girls to "just be mothers", is it then OK to describe a woman as "just a mother"?
I have a daughter. I suspect that if she becomes "just a mother", what that really means is her skills and interests are so foreign to me that I can't come up with a better description than "just a mother". And I hope that I will not be OK with that.
You need to stop treating everyone in the world like a member of your scrum team or something. Understanding people's "skills and interests"? They're just people for crying out loud, speak to them. And no, there's nothing wrong with being "just a person". Stop being so analytical and desperate to have everything conform to your fantasies of what the world should be like.
Like in the original comment this started with "girls just want to be mothers" is contrasted with being a person who has any out of parenting interests at all.
And for all the talk about "noble", no interests at all leaves you with nothing to think about, nothing to talk about, nothing to do, nothing to be happy about when children are not present. Nothing to be proud about once the kids are not toddlers anymore and their achievements are their own.
Speak for yourself. Sounds like projection to me.
Do you have children? Parents can be very proud of their children's accomplishments.
And parent "living exclusively through childrens achievements" is object of criticism. That situation is not good for children, because they end up being pushed into parents dreams. It is unfair to children to expect them to be your source of proudness or whatever.
