I can't believe my sister is having a baby! Isn't it amazing? Why are you looking at me like that?
I'm just not as impressed with procreation as you are.
It's a miracle, a miracle of life. Surely that has to amaze you.
Nope, 'fraid not. I know, if we wanted to, we could have a baby immediately, without any effort, both wearing scuba gear. No watching your cycles, no nothing. Instant baby.
But that normally isn't the way it works...
Believe me, honey, sperm is like a wild animal. They smell fear and they attack. Let's not talk about it anymore. They might hear us.
