The cost that childless people pay is: they don't have a child. That's not a good thing, in fact it's very depressing to be 30 years old and still in school while other people are having babies.
This girl wants it both ways. Perhaps we should also entitle single people to enjoy the company of other people's kids, just to keep things fair.... I should have a right to play at the park with toddlers, or teach someone's boy to ride a bicycle. Society owes me this!
I see lots of haggard, graying PhDs with very young families. They got what they wanted first. The youngest of my 3 sons turned 18 a few days before my 49th birthday. The middle son graduates from college this Saturday. The oldest son is 26 and still living at home. At least he's still living after 4 open heart surgeries, 2 artificial valves and a pacemaker. He gets up and goes to work 5 days a week.
