I hate having them. Really, I do. My friend Sara has no children, no mortgage, none of that. So what did she do? She ran off to Washington to live with a drummer. She has a day job, but by night she's this total hippie drunkard with no rules. Not neccassarily saying that's what I'd do, but it's funny to look at the differences in our lives now.
It's always entertaining to look at other people's lives and see what you would wish differently for your own.
I'm on the other end. With Josh gone for a few years now, I would rather have more kids at home and be doing the family thing for quite a few more years. For me, this less responsible lifestyle isn't much fun.
