An error message

An error message walked in through the door!

Okay, fine, it didn't really walk through the door, but it may as well have with how much it scared you. Somehow, the book made a blaring sound like an "incorrect" buzzer, and a note flew out.

"RULETYPE UNDEFINED: Use OLD or NEW keyword."

Oh yeah, the "old rule, new rule" thing. You totally forgot.

You thought about it carefully; which keyword should you use?

If you choose NEW, you'll be able to revel pervertedly in the horrified reactions of all the (other) women growing their new bulges, but international politics are going to get really messy, and you'll be spammed with requests for advice on how to use it (though maybe you want that, so you can demonstrate hands-on?)

If you choose OLD, you'll be able to go about your life again without worldwide panic, and women's clothing will be tailored for your "old" bulge, but you could forever change the course of human evolution of it goes back too far.

So what's your choice? Chaos or normalcy?
