I don't know if it really answers the question but I always say that it's everyone's perogative to be naive and idealist before they have children and also their perogative for that to come back and bite them on the ass once they have kids
So I'm not sure if I would say I'd blame being childless for making an odd or out of place comment, I would certainly take it into consideration. Just the same as if a pilot told me what I should do with my broken TV, I wouldn't blame the fact they were a pilot for the questionably advice, but I would take it with a grain of salt because it had come from some one with little experience with the subject at hand. I think it is silly to say it isn't relevant when you are comparing the opinions of some one with years of experience to some one with no experience. Unless I guess unless it was a medical opinion i.e. a Dr or nurse would know more than me about chicken pox in children even if they hadn't had experience treating it. But I don't get the impression it was a medical opinion coming from a qualified health professional....?
