oh yes, it sounds familiar. When I was young I tought life would be FULL. I mean, be good or bad times, I thought I had a tasty mouthful. Now time has passed, I'm approaching 40 and nothing happened. And I say "so what?". You see, I have no wife, no kids, no house (I live with parents). YOur story tell me that if I had accomplished a lot that wouldn't make difference...

Yes, correct, children are kept in a kind of safe world where everything is colorful and fantastic (this applies to fortunate children of course). Then the child grows up and we tell him "ok you're grown up now, it's time for you to find out the truth. here is a truckload of xhit to eat!"
Better to tell them what life is like sooner? Or better yet NOT have kids?
