You don't have children because it's easy. If resume responsibility of any living thing with the concept that it would be a piece of cake, then you're probably the last person on Earth who should do so. Just sayin'.
Ummmm....babies do claw and bite even without going to the doctor. Toddlers excel at kicking you in the nuts and mysteriously finding your nipples even when you have a bra, shirt, and sweatshirt on.
(Sorry I offended some of you)
You hate kittens as well don't you?
