Not wanting to touch another person’s piss and shit isn’t “trivial”. It is to you, because you have a stronger constitution for that sort of thing, but anything that makes you unhappy is not a “trivial” reason to not have kids. Do you think your kids would have grown up well-adjusted with parents who hated every minute of caring for them?
You might as well tell me my reasons for not following my mum into nursing (squeamishness and general disdain for humanity abs it’s suffering) are trivial. So tell me, should I go onto the caring profession and become the next Beverley Allit?
