Weaning a baby... My wife has done that 5 times. It is the natural course of things. What I haven't seen her do is stick her hand down her throat and rip a 15 foot tapeworm out of her gut. That's Social Security Reform.
"...and rip a 15 foot tapeworm out of her gut."
I like my analogy better. A tapeworm doesn't need to be replaced with anything after you rip it out.
