Being in a successful, loving, long-term relationship is a sign of maturity and cooperation.
Being able to raise a child is a sign that you can think and love beyond yourself.
Being able to cook for your loved ones and keep a clean, inviting house for them to return to means you value achievements that may not be obvious from the start, and that you know the difference between a house and a home.
I think modern dislike of these things is actually frustration that, in a world of instant gratification, the things that really matter take hard work and dedication to earn. They should not be rejected, but worked on!
