Parenting has made me a believer in karma. Good buddy of mine back home was an absolute scumbag in his 20s, womanizer and philanderer of the worst sorts. Almost as bad as Ender, but with humans instead of various farm animals. After more than a decade of it, he decided it was time to settle down, and the new wife (a former lingerie model too, fair play) immediately got pregnant and he started freaking out. "I'm in trouble, Gaz. I know karma's coming for me. It's going to be a girl, she'll grow up to be gorgeous, and I'll have to deal with every boy in town sniffing around the house."
He was beyond right.
Bumped into him on a visit back five years or so ago, we were back doing a naming ceremony for ours, looked like he was in his mid 60s, what little hair he had left was grey, and he had the faraway stare of a man who'd seen too much. "Daughters, Gaz" he said, trembling hand holding a , "When you have a boy you only have to worry about one c**k. When you have a daughter you have to worry about all of them."
I wasn't a great person myself in my 20s, and now eyeing the future with considerably skepticism. (And pondering a nunnery.)
