Good discussion, i am 46 and my wife is 39, we are both very proud parents to our son Sam, who is 5, and our daughter, Neve, who is 18 months.
I would have to say that i was a bit apprehensive about it all, given my age, but also being around long enough to see them grow up and be happy.
We are both young at heart, so i think, its your business what you do, bugger what others think, and for what its worth, i would certainly let the idiot/idiots know exactly how i felt if i was to hear that sort of crap.
