If I'm insulting anyone, it's only out of genuine concern rather than intent to denigrate. I don't want them waking up one day at 45 realising they've missed their chance and have 40+ long years of emptiness and regret to reflect on their mistake. I don't want them observing the demographic changes around them with overwhelming guilt for their doing nothing.
I want them to experience the joy and fulfilment of family. Parenthood fundamentally changes people. I see it. You do too.
