Did she find the genes that make boobs a Double-D?
If not, tell her to hurry up.
I don't know if genes are involved. While the women on both sides of my family have respectable racks, I'm the only D/DD (depends if it's a regular or push-up bra). You know how I got 'em? Force of will. I am not joking. Some people with supernatural brains can bend spoons or move objects. I chose to use part of my brain power on this. Sure, I coulda maybe devoted my entire brain to figuring out time travel or something, but I don't regret my choice.
